Resolved Issues

Cross-Section Collection Center Shifted in Y-Axis After the Scan

After a cross-section scan is finished, the stage is shifted in Y axis for some microns from the cross-section collection center set in the mosaic before the scan. After sending the map file to Altus, the wrong shifted center spot is saved in the map file and causes confusion which is the true sampling location (mismatch was observed in Y direction).

Cross-Section Scan Taken at Wrong Stage Z-Position

During a cross-section scan, the stage moved to the most recent of either the focal position of the most recent experiment setting or the initial Z position from when the software was started. It then acquired the scan at that position instead of the specified one.

Spectral Series Acquisition Never Completes

When collecting a spectral series, the acquisition would never complete, and the software would become unresponsive.

Spots Appearing in Images with OMNICxi

When using a DXRxi with OMNICxi, depending on the collection parameters, the instrument occasionally missing a spectrum at a position. If this happens during the first scan, it appears as a black spot and there is no spectrum associated with the position. This may also happen on subsequent scans, but it is not as obvious because there is already a spectrum associated with the position. This results in artificially lowered intensity at those spots.

Unable to Open Map File

Starting with OMNICxi 2.3, maps containing no spectral data cannot be saved. This had the side-effect of preventing old map files with no spectral data from being opened. The software now opens those files and presents a warning to the user about the lack of spectral data.

USP Performance Verification (PV) Presents Different Results in Printed Report Than On Screen Report

The printed report gives different Test Names, Measured Values, and Results for the Peak Area Delta tests.

Known Issues

OMNICxi v1.2

Release Date: May-2015

Supported Operating Systems

Windows 7 64-bit

New Features

Time based map collection

This version adds the ability to collect maps at specific time intervals or based upon an external digital trigger. Time interval collects maps at a specified time interval (start of map to start of next map). It will collect a set of frames that can be viewed in the analysis window using a new map image player to view the frames.

The trigger based collect uses an external USB digital IO box to start each map. There are also digital outputs to synchronize when the map collection is in progress and when all the maps are complete. The maps can be viewed in the same manner as the time interval maps.

60X objective

The 60X objective has been added to the list of possible objectives to use.

Filename can be defined prior to map collect

The filename for a map can now be defined prior to collecting a map by using the Save Map button to define the new filename, As the map is collected, the data will be written to the new location. When New Sample is selected, the filename will be forgotten so the software will not overwrite the previous file.

Early Analysis window update

When a new set of regions are collected, the Analysis window will be updated with the new region at the completion of the first region collect. As other regions are collected, they will not automatically be added to the Analysis window, but a button at the top of the Analysis window will be highlighted in green to show more data is ready to add to the window. Clicking this will update the Analysis window with the new data. At the completion of collecting all the regions, the Analysis window will be updated automatically.

Time based maps viewing

When time based maps are collected, there is a new control in the Analysis window that allows viewing the time frames automatically or manually. Using the play button will start showing maps at about 1 per second. Clicking the fast forward button will increase the speed of the update. The stop button will stop playing the maps. The current index and time of the frame will be shown at the bottom of the control set.

The maps can also be selected by sliding the frame selected control up or down. The is also an up and down arrow control to step one frame at a time.

Delete regions from map file

Regions can now be deleted from a map file loaded from disk. It does not allow deleting all the regions. There must be at one region in the file after deleting regions.

Tiff files contain region information

Tiff file save has been improved to include region information tags in the file to allow easy loading of files into other applications with registration of the regions.

Time based tiff file saves all the frames from a region into one file with the region information for easy display of a large number of frames.

Time based regions spectra extraction

Spectra can be extracted from a single time frame or from all time frames at one location. This also applies to the spectral average function.

Time based map frames can be removed

A right click menu is available to remove frames from either end of a stack of frames.

Auto spectra average

Spectra can be auto averaged using the nearest neighbor when using the spectrum selection tool. There is a right click menu item to turn this feature on or off.

Doubled speed of opening files from disk

When opening a file from disk, it will open faster than in previous release.

Improved speed of profile calculation

For profile types other than MCR, the calculation speed has been doubled.

Resolved Issues

Invalid correlation spectrum

When a reference correlation spectrum is selected from disk that does not match current settings for map spectra, the operator is prompted to select a different spectrum. When one is selected prior to collection and it is not valid for use, a spectrum from the data set will be used instead, This prevents blank correlation spectra.

Error from illegal spectral range in profile

When a spectral range outside the range of the data being collected was set in a profile, there were sometimes errors. This has been corrected to allow only legal ranges for the data available.

Improved mosaic and map data transparency

When using the transparency with data that fully overlaps, all data sets were visible. The transparency will work correctly for full overlapped regions.

OMNICxi v1.1

Release Date: Dec-2014

Supported Operating Systems

Windows 7 64-bit

New Features

Translations

The translations of the software are now included for the following languages: German, Spanish, French, Italian, Japanese, Russian and Chinese.

Add 5x and 60x objectives

The 5x and 60x objectives are now shown.

Browse button for setting default save folder

The folder for the default location to save maps can be browsed to with a browse button.

Non square cross sections

Cross sections of non square shape can now be defined using sliders for the two dimensions. Also allow deeper cross sections.

Peak width profile added

Peak width profile has been added. The peak location and the method of calculating the peak width can be defined for the profile. This also has a threshold value to filter values when no peak is present.

Peak position profile updated

A peak threshold value has been added to the peak position profile to filter values in spectra that do not have a peak.

Zoom to world

The zoom to world button on the mosaic pane of the acquisition window will zoom to the size of the regions collected if no mosaic is collected.

Live video image size

The live video size will now remain the same no matter how the survey region size is changed.

Selected spectra indicator

The location of the selected spectrum or multiple spectra is indicated on the region for each spectrum.

Add “Unknown” as search result

The search result “Unknown” has been added to be used in a search to be used if the search does not find relevant hits to the selected spectrum.

Changes for Queue window

The queue window can be moved to allow viewing all of the mosaic or other sections of the application. A select all regions button has been added to facilitate use of regions.

Profiles update when profile type changed

The will be recalculated when the profile type is changed except for MCR which has an apply button after setting it up.

Profile value shown

When clicking on spectra in the Analysis window, the value calculated for the profile is shown to allow viewing exact profile results.

Viewed spectrum indicator

When a spectrum is selected from the map, a symbol is shown to indicate the location of the spectrum on the map.

Enhanced map color selection

Three new color ranges have been added that range from black to either red, green or blue to show the low amplitude profile results as black instead of white.

New mosaic collect start point

When collecting a new mosaic it will start collect from the current stage position so that stage not moved from selected location.

Resolved Issues

Joystick locked out during align and calibrate

To prevent accidental stage movement during align and calibrate, the joystick is locked out.

Collected regions values adjustment

The values on the acquisition window sliders are disabled for regions that have been collected.

Region size control

The lower left corner of the region can be used to change the size of the region.

File open fail mode

When file open fails, the software will be reset as if the new sample button was pushed.

Send library spectra to OMNIC

Sending library spectra to OMNIC is disabled.

Units after align and calibrate

Units will be consistent with selected units after align and calibrate.

Do not allow multiple objectives in mosaic

Limit mosaic collect to one objective size.

Report the actual time in queue

Report the actual time of a region collect in queue.

Changed report information

Fix pixel size and number of spectra values in report. Change to show table as two tables so can be seen on one page of report.

Correct misaligned Filter/Grating error

An error occasionally seen during align and calibrate regarding the filter and grating has been corrected.

Cross section coordinates

Fixed reported coordinates shown in cross section for cross section image.
