LIFEx reads DICOM images locally or over a network using a DICOM browser and includes a powerful 3D reconstruction-based slice viewer. Volume of interest (VOI) can be either imported from previously created files or drawn and manipulated using LIFEx. Results are exported in Excel format files. LIFEx runs on Windows, MacOs and Linux. It is distributed with examples and includes a tutorial. User support is offered. Users can optionally contribute to the gathering of index values in different tissue types and different images as a public data bank of reference values is currently being built and integrated to the software for assisting the users with the interpretation of their results.

What has been added, changed or updated in this new release?
Here is a list of the most significant additions, changes or updates in LIFEx v7.1.0:

- added: GML and GML1 units on TEP series
- added: arguments (script, image, directory) on command line
- added: display header of all loaded dicom files (and not only the first file)
- added: protocol box size reduced after five minutes
- improved: display of images and ROIs
- improved: the dialog boxes for protocols not used for 10 minutes are automatically minimized as an icon
- changed: save MIP 360° is mp4 format with rotation of 2°
- fixed issue: no freeze when mouse move out of MIP frame while recording MIP in MPEG4 format
- fixed issue: rtstruct.dcm save

Main (ROI):
- fixed issue: reading of some RTStruct DICOM that could not be read properly before
- fixed issue: nifti multi-ROI file with IOP and large number of ROIs (>100)
- fixed issue: contrast-based segmentation method
- fixed issue: RTStruct with image orientation in patient coordinate (IOP)
- fixed issue: clickDraw and clickDraw40% sometimes frozen
- fixed issue: colour mixing of overlaid ROIs
- fixed issue: on pencil2D, Nesle, Threshold tools
- fixed issue: W/L threshold tool: active even if no ROI yet

Texture protocol:
- removed: button of ROI check for texture
- added: correlation map on local map texture
- added: add key=value LIFEx.check=true in texture script
- changed: thresold of 0.1SUV to calculate texture-GLCM-map (in place of 0.05#)
- removed: comment of peakSphere1mL and 0.5mL Columns in texture result file
- fixed issue: suppression of the +1 in the discretization values only for values > maxBound (for IBSI compliant)

Quality Control protocol:
- add CT transverse
- add PT PSF

Labelling protocol:
- added: multi serie loading with input parameter all.patient.img#.color all.patient.img#.window.width all.patient.img#.window.level available

- fixed issue: quarter symbol (BR_, BL_ TR_, TL_) are now always written to the result file

- fixed issue: the following html symbol 
is now converted to a line feed in the .csv file
