External Email - Use Caution Hi: I have Ubuntu 18.04.4 LTS and freesurfer release freesurfer-linux-ubuntu18_x86_64-7.3.2-20220804-6354275. When I run freeview, I got the error: "This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem. Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, webgl, xcb." How can I correct it? Sincerely, Gonzalo Rojas Costa

Tracula -bedp and -prep exited with errors

External Email - Use Caution Hello, The following command trac-all -c dmrirc.example -bedp always exits with the following error. { WARN: Running bedbostx locally - this might take a while WARN: It is recommended to run this step on a cluster bedpostx_mgh -n 2 -model 1 /home/developer/Desktop/DATA_VB/Data/TRACULA/trc/Sub_01/dmri /usr/local/freesurfer/7.4.1/freesurfer/bin/bedpostx_mgh: 128: /usr/local/freesurfer/7.4.1/freesurfer/bin/bedpostx_mgh: Syntax error: "(" unexpected } The processing doesn't even get started. It exits immediately I tried freesurfer 7.2 and 7.4.1 versions on virtual box thinking there might be some problem with the bedpostx_mgh source code. But it does the same with both the versions. Trac-all with -prep argument runs for a while and exited with { Pre-sorted training .trk file detected INFO: Rejected 114 streamlines for straying off mask INFO: Rejected 0 streamlines for reversing direction INFO: Have 19886 total streamlines (min/mean/max length: 60/88/115) Processing pathway 29 of 42...

Re: [Freesurfer] Any chance at all for an official proper fix for Freesurfer on FIPS?
by fsbuild 25 Jul '23

25 Jul '23

External Email - Use Caution My understanding is no environment variable setting like OPENSSL_FIPS=0 will allow md5 or other algorithms found in linux open source code to run which are not allowed under FIPS, e.g., see list, docs.oracle.com/cd/E36784_01/html/E54953/fips-notok-1.html Barring any environment override to turn off FIPS, and assuming you can’t boot into a non-FIPS enabled kernel to run Freesurfer, then one alternative could be to run a container or VM that is not FIPS enabled and in turn run Freesurfer in that.  That container/VM could be constrained with specific userids,  limited mount points, limited network connections, etc. There are examples of users running (even cloud based) container instances where they need to disable FIPS in order to run software/services, http://secure-web.cisco.com/1YPySRXdxKA8W9FNheIf6NOl70aLbr0Kl0TeGnNEk89j6ZU… We currently don’t have resources to test Freesurfer in a FIPS environment.  But I would not expect FS to run under FIPS given the list in the above link.. - R.

Questions for the estimated brain volume based on new version of FreeSurfer
by Yoonho Hwang 25 Jul '23

25 Jul '23

External Email - Use Caution Dear FS developers, Hi, I am very happy that we can use new features of FreeSurfer (e.g., recon-all-clinical.sh, SynthSeg, SynthSR, etc.) While using a variety of functions from FreeSurfer (v7.3.2 and v7.4.1), we would like to hear the answers to the following questions. 1-1. Compared to the recon-all stream, using SynthSeg seems to overestimate the volume in many subregions of the brain including eTIV? Can you explain why this happens? 1-2. The estimated volume of the entorhinal cortex is different between recon-all/SynthSeg and recon-all-clinical.sh. There is a 3-4 times difference. Can you tell me why the result is? 2. Can the functions (segment_subregions, segmentThalamicNuclei.sh, segmentBA.sh, segmentHA.sh, etc.) used in recon-all be used in recon-all-clinical.sh? Please let me know if there is anything you don't understand. Looking forward to your feedback. Thank you very much.

Possible bug: recon-all -i $T1 -T2 $T2 -autorecon1 attempts to run -T2pial
by Christopher Markiewicz 24 Jul '23

24 Jul '23

External Email - Use Caution Hi all, This is a reproduction of GitHub issue 1010. There is a section of recon-all (L5927-5930 in current dev) that states: # MOD: turn on T2/FLAIR pial editing when FLAIR specified # This can backfire, eg, if not all the preceeding steps # are included set DoT2pial = 1; This seems an intentional decision to make -T2 activate -T2pial (and similar for -FLAIR), which I suppose is a response to people running `recon-all -i $T1 -T2 $T2 -all` without `-T2pial`. However, it also activates with -autorecon1 and -autorecon2, which will not run -pial before -T2pial. Would you all consider this a bug or a caveat emptor kind of situation? Would it make sense to add the following to -autorecon1 and -autorecon2 (hopefully this formats okay)? diff --git a/scripts/recon-all b/scripts/recon-all index 4b98118264..0655097ab9 100755 --- a/scripts/recon-all +++ b/scripts/recon-all @@ -6869,6 +6869,7 @@ while( $#argv != 0 ) breaksw case "-autorecon1": + set DoT2pial = 0; set DoCreateBaseInput = 1; set DoMotionCor = 1; set DoTalairach = 1; @@ -6911,6 +6912,7 @@ while( $#argv != 0 ) set DoRemoveNeck = 0; set DoSkullLTA = 0; set DoSegStats = 0; + set DoT2pial = 0; set DoCANormalize = 1; set DoGCAReg = 1; set DoCALabel = 1; In any case, I am now adding -noT2pial and -noFLAIRpial to -T2 calls that aren't -all as well, which seems safe for writing commands that will work for both FreeSurfer 6 and 7. Thanks, Chris
