OsiriX MD Full-Featured Version (from $69.99/mo). Get OsiriX MD, the complete edition of OsiriX. With ultrafast performance and an intuitive interactive user interface, it is the most widely used medical images viewer in the world. Mac shares how his songwriting has evolved since he first started making music, his first “aha” moment as a writer, and the experience of performing live on tour. At the end of the episode, Eric plays “Jumping Off The Moon,” an impromptu collaboration with Mac from the same day in the studio. Eric Krasno Plus One is presented by Osiris. Installing and upgrading OSIRIS. OSIRIS Windows instructions. OSIRIS Macintosh instructions. Attention Mac users with OSIRIS version 2.12.1 and earlier - With newer versions of Mac OSX, sometimes the OSIRIS windows do not appear. This can be remedied by clicking on the OSIRIS icon in the dock (usually at the bottom of the screen) to activate the OSIRIS window. Osiris, also called Usir, one of the most important gods of ancient Egypt.The origin of Osiris is obscure; he was a local god of Busiris, in Lower Egypt, and may have been a personification of chthonic (underworld) fertility.By about 2400 bce, however, Osiris clearly played a double role: he was both a god of fertility and the embodiment of the dead and resurrected king. Osiris is a beautiful game that uniquely combines inventive crafting, curious exploration, and skillful FPS combat gameplay that highlights the beauty and horror of exploring a foreign, yet gorgeous alien system - an experience that's neither safe nor for the timid.

Version 2.14 Release notes

Version 2.14 includes major new features.

New Features

Simplified printing

  • Version 2.14 introduces Simplified printing of both individual views and entire analysis batches. Single samples may be printed and is customizable via the onscreen view so that labels, thresholds, channels and views will print as displayed on the screen. Entire analysis batches can be printed and customized to display as the user desires, including labels, thresholds, Y-axis ranges, X-axis range in base pairs or time, and the number of channels per page. The number of channels per page can be customized individually for ladders, negative controls and samples to optimize the display of peaks and peak labels for ladders and samples with many peaks. Print color intensity can be optimized for different printers.

Peak and label colors

  • Peak and label colors have been adjusted to make both more easily distinguishable if a label overlays a peak.

Improved analysis robustness

  • Analysis has been improved to prevent poor quality samples from occasionally causing an entire analysis to fail. Additional error messages have been added to explain why samples or analyses failed.

Analysis correction function for artifact peaks

  • Occasionally, poor data quality in the ladder controls or sample internal marker ILS makes it impossible for OSIRIS to analyze. A function has been added to accept a list of peaks in the ladder or in the sample ILS that should be ignored to allow the software to recognize the correct known peaks and complete the analysis. This allows users to rescue ladders and samples.

Running OSIRIS from the command line

  • An explanation of how to run OSIRIS from the command line has been added to the User’s Guide, so that OSIRIS can be called by other software without the need to start the user interface first. This allows OSIRIS to be incorporated into a computing workflow or into other software.

Added homozygote threshold settings

Osiris For Pc

  • Added a setting that prevents a “Homozygote too low” artifact in positive control samples.
  • Added a homozygote threshold above which a peak is considered to be a valid homozygote even if peaks are found between the Min RFU Analysis threshold and the Detection threshold.

Removed off ladder allele setting

  • The setting “Do not call OL allele if pull-up” was removed to prevent the possibility of a valid allele not being called if it also contained signal from a pull-up, given that the current pull-up analysis algorithm deals appropriately with that situation.

Changed uncertain pull-up artifact priority

  • Changed the artifact priority of “Partial Pull-up Uncertain” peaks, where the pull-up algorithm is unable to determine a pull-up pattern, from non-critical to conditional. If the peak is pure pull-up or partial pull-up corrected below minRFU from another channel, pull-up uncertain is non-critical. Otherwise, it is a critical artifact to ensure analyst review.

Bug Fixes

  • Fixed a bug that in certain circumstances could have prevented the maximum threshold artifact from being triggered when a peak’s height exceeded the maximum RFU threshold.
  • Fixed a bug in the baseline offset calculation that would prevent analysis in rare circumstances where dynamic normalization was not selected.
  • Fixed a bug that caused off-ladder alleles to trigger a non-critical artifact at the peak level, but a critical artifact at the locus and sample level. Off ladder peaks now give a critical artifact at all levels.
  • Fixed a bug introduced in v. 2.12.2 which caused sigmoidal pull-up to be called as partial pull-up rather than pure pull-up and to receive an allele call in addition to the artifact, if above the analytical threshold.

Version 2.13.1 Release notes

Version 2.13.1 corrects version data in three kit Operating Procedures that prevents settings from being changed.

Bug Fix

  • Corrected the version data in kit Operating Procedures that prevented them from being saved as a custom Operating Procedure with changes to the lab settings in OSIRIS version 2.13. The following Operating Procedures that could not be modified in version2.13 will function normally in version 2.13.1. This change has no impact on the accuracy or results of analysis in OSIRIS beyond the ability to use these Operating Procedures.
    • [IdentifilerPlus w/o ILS @250]
    • [NGMSElect]
    • [SEfilerPlus]

Version 2.13 Release notes

Version 2.13 includes major new features.

New Features

Fragment Analysis

  • Version 2.13 introduces size-based fragment analysis using an internal size marker, without the need of an allelic ladder. This allows users to analyze home-made multiplexes without needing to construct their own fragment size ladder. Included are Lab Settings that allow analysis of 2, 3, 4, and 5 channel analyses, and settings to allow users to designate the channel in which the marker data resides.

Flexible export formats

  • Added an export that allows users to format their data export without any programming, so they can easily export in multiple different formats for downstream use or processing. Users can choose the type and order of the data they are exporting and whether they want a row to be a sample, a locus, or a peak.

Simultaneous Mixed/Single Source Analysis

Osiris Dicom For Mac

  • OSIRIS can apply the stutter-, adenylation-, fractional-, and pull-up fractional-filters differentially to single source samples (knowns and references) and possibly mixed samples (casework or chimerism study samples) that are in the same analysis run. Sample type can be detected by matching character strings within the file or sample name. This can be particularly helpful when running reference and mixed samples, either to reduce the amount of editing of the reference samples or where the exported data will be used in mixture analysis software that requires stutter peaks to be called. Added settings to allow either sample type to be the default and to allow character strings to specify the other sample type, simplifying use of this function.

Use of Non-Roman and Other Unicode Characters

  • OSIRIS now allows use of non-ASCII characters in file paths and filenames, so international users can use non-Roman and other Unicode characters in directory/folder and file names.

Identify Lab Settings Folders

  • OSIRIS now allows users to easily identify and find the location of Lab Settings folders. Clicking the folder icon button in the Lab Settings window will open the parent folder with the Lab Settings folder selected. This allows users to zip or compress the Lab Settings folder for easy exchange.

Bug Fixes

  • Fixed the Mac version of OSIRIS so that windows open correctly with the latest version of the Mac OS Software. (Fixed in both 2.13 and 2.12.2.)
  • Fixed a bug that could prevent analysis in RAPID-DNA samples that had high levels of noise.
  • Fixed a bug in the pull-up algorithm that incorrectly applied the spike artifact to some peaks that were not spikes.
  • Fixed pull-up identification bugs that existed in previous versions that in rare circumstances might have prevented calling pullup but would not have prevented alleles from being called.
    • Fixed a bug that in rare circumstances prevented suspected pull-up crater side-peaks and sigmoidal peaks from being called as pull-up.
    • Fixed a bug in the pull-up algorithm that did not identify some pull-up peaks because the peaks were wider than expected.
    • Fixed a bug in the pull-up algorithm that failed to identify some spikes.

Version 2.12.2 Release notes

Version 2.12.2 fixes bugs in the pull-up identification algorithm and in opening windows on the Macintosh version.

Bug Fixes

  • Fixed a bug in the pull-up algorithm that prevented flagging sigmoidal peak artifacts. A positive sigmoidal side peak could be flagged as a possible off-ladder allele, requiring additional editing.

  • Fixed a window display issue on the Macintosh caused by changes in a Mac OS update. In certain cases, Mac users would need to click the OSIRIS icon in the Dock at the bottom of the screen to display a newly opened OSIRIS window. The fix causes windows to open correctly with the latest version of the Mac OS Software.

Version 2.12.1 Release notes

Version 2.12.1 fixes a bug that prevents the COrDIS kit from working.

Version 2.12 Release notes

New Features

Improved Artifact Analysis

  • Improved pull-up reporting so that pull-up is not reported when the pull-up peaks have no impact, such as when the pull-up is below detection threshold or is negative in the raw data.
  • It is no longer necessary for the user to specify a minimum height below which a peak will not cause pull-up. Added a pull-up analysis setting to allow the OSIRIS pull-up algorithm to calculate the parameter from the sample data. This makes the algorithm accurate over a broader range of data, and relieves the laboratory of having to empirically determine a value. We strongly encourage users to take advantage of the new “Primary Pull-up Threshold: Computed” setting.
  • Improved pull-up analysis use of peak saturation data.
  • Improved pull-up analysis where primary peaks have significant noise
  • Improved analysis of split peak “craters” by taking peak widths into account.

New Kit /Lab Settings

  • Added the COrDIS kit

Usage statistics

OSIRIS version 2.12 collects non-identified usage statistics to help us improve the software. It does not collect information on samples, profiles, batches or information that would reveal the context of the analysis. Users can opt out or disable the statistics reporting. Details are in the Privacy Information section in the appendices of the User’s Guide or see Privacy Information on the Help page.

Bug Fixes

  • Fixed minor bugs that did not impact accuracy.
  • Fixed a bug in normalization algorithm that in rare cases could cause a spike in normalized data. This would not have caused incorrect allele calls.
  • Fixed a bug that prevented the peak residual from displaying in the allele hover box when the residual was zero.
  • Fixed a bug that could cause OSIRIS to crash on the Mac under rare circumstances.

Version 2.11.2 Release notes

Version 2.11.2 fixes a bug that could occur under rare conditions, causing a sample to fail if the bug is triggered.

Bug Fix

Baseline bug

Fixed a bug that under rare circumstances, with a particular lab setting combination, could cause intermittent analysis failures of certain samples. When the bug manifested, certain array values were not initialized. The result was an off-scale raw data baseline in one or more channels causing the channel to not analyze. The bug had absolutely no impact on the accuracy of any successful analysis.

Osiris

The bug fix in version 2.11.2 has been tested with 33 samples and settings that intermittently triggered the bug to demonstrate that the results of analysis with version 2.11.2 is identical to successful analysis with version 2.11.1, including allele calls, peak RFU, peak bp size, artifact calls, etc.

This bug does not affect versions prior to version 2.11 or version 2.12 and higher.

Version 2.11.1 Release notes

Version 2.11.1 fixes two bugs that could occur under rare conditions.

Bug Fixes

Pull-up analysis bugFixed an uncommon bug that in extremely rare circumstances could result in an allele that comigrates with a peak in another channel being called a pull-up in circumstances where the “Min RFU for a peak to be considered as a peak that causes pull-up” in the Sample Limits tab of the Lab Settings is set too high.

ILS peaks with no labelFixed a bug in which ILS peaks that were also called as pull-up were not given a base pair label. While this produced no analysis errors, it could result in display issues.

Version 2.11 Release notes

New Features

Improved Display

  • OSIRIS now allows users to display either Time or Bases on the x-axis of the Graph view.

Improved Artifact Analysis

  • Allele-specific stutter analysis has been added as an option. Allowing the stutter threshold to increase with increasing allele size gives more accurate discrimination between alleles and stutter. Users can set their own threshold levels.
  • Allele peak heights corrected for coincident pull-up signal can be used in stutter and adenylation analysis when determining whether a peak falls under a threshold, to make discrimination between alleles and artifacts more accurate.
  • Improved pull-up analysis by including low-level raw data peaks below analytical threshold in the overall pull-up pattern analysis, resulting in better identification of very low level pull-up peaks.
  • Added settings to reduce the possibility of extraneous “excessive residual displacement” artifact calls.

Osiris Machine

Improved Baseline and Peak Analysis

  • Added options for improved peak curve fitting at the base of large peaks, which can also improve the analysis of low level shoulder peaks.
  • Improved baseline estimation at the edges of peaks.

Process Quality Control Metrics

  • Multiple metrics have been added that can be exported for quality control of the DNA analysis process. This includes data regarding the performance of the genetic analyzer and sample extraction/amplification to allow predictive monitoring for issues like poor spectral color separation matrix, capillary failure, and extraction/amplification problems.

Improved Editing

Osiris Form

  • Reduced editing due to artifacts in ILS and ladders. Many minor artifacts do not impact the spacing, accuracy and validity of ILS and ladder profiles, but previously required editing. Options have been added allowing users to specify that artifacts that do not impact ILS or ladder validity be non-critical and not require editing. These artifacts are still called and displayed for review.
  • Added options to allow editing of “restricted priority” peaks and peaks that are below analytical threshold (and above detection threshold).

Improved Network Administration

  • Implemented shared Lab Settings and Export settings in a network environment where both Windows and Macintosh versions of OSIRIS are in use.
  • Improved the management of user permissions for Lab Settings and Exports.

Improved CODIS CMF file exports: Can include comments in the Sample Comments field of the Plate Template in the ABI Genetic Analyzer Data Collection Software that OSIRIS can export to the CODIS CMF Comment field.

Improved ladder analysis: Improved robustness of bi-allelic loci, such as Amelogenin. Reduces artifacts.

New Kit / Lab Settings

Added example Lab Settings for Sole Source and Mixed samples

PowerPlex Fusion HID Sole Source and GlobalFiler HIG Mixture lab default settings include all of OSIRIS novel features and updates and can serve as a starting point for laboratories to optimize their settings for sole source and potential mixed samples. Both can be modified for use with .fsa files, and the settings can be copied to other kits. Both will need to be modified for lab’s own analytical thresholds and desired peak sensitivity.

Bug Fixes

Pull-up analysis bug

Fixed an uncommon bug that in extremely rare circumstances could result in an allele that comigrates with a peak in another channel being called a pull-up. This bug was fixed by making better use of peaks that did not comigrate with a peak in the pull-up channel, or that comigrate with raw data above the noise level for the channel.

ILS peaks with no label

Fixed a bug in which ILS peaks that were also called as pull-up were not given a base pair label. While this produced no analysis errors, it could result in display issues.

Fixed minor bugs that did not impact accuracy
