Missing freesurfer files after running recon-all
by Taylor, Lisa Marie 15 Jul '21

15 Jul '21

External Email - Use Caution Hi everyone, I could really use some help with figuring out an issue I've been struggling with the last few months. It seems that when I run recon-all on over 20 of my participants, not all freesurfer files are created. But I am not understanding why, and my technical capabilities are limited. Particularly, it seems there's an issue reading the lh.BA1_exvivo.label. I will attach a screenshot of a participant who has all the expected files vs. a participant who is missing important files. I will also attach the recon-all log file for any other information that it can provide. Also, I run a script for recon-all and these are the arguments: srun ${FREESURFER_HOME}/bin/recon-all -s imagedir/subid -no-isrunning -all -hippocampal-subfields-T1 -brainstem-structures -qcache Not sure if this is pertinent, but our HPC has been updated, but I am unaware if that can impact how freesurfer is run. Thank you for any insight you can provide! Lisa ________________________________ This message may contain confidential information and is for the sole use of the intended recipient(s).

Problem with mri_glmfit-sim
by juergen.haenggi＠upd.unibe.ch 15 Jul '21

External Email - Use Caution Dear FS experts I have run stats using mri_glmfit (FS 7.1.1 on Mac) with the following command mri_glmfit --y IPS_2groups_n135_lh_thickness.10.mgh --fsgd IPS_fsgd_2groups.txt --glmdir IPS_2groups_n135_Thickness_LH.glmdir --surf fsaverage lh --C IPS_2groups.mat --cortex and everything worked fine. When trying to run simulations with mri_glmfit-sim with the following command mri_glmfit-sim --glmdir IPS_2groups_n135_Thickness_LH.glmdir --sim mc-z 500 1.302 lh_mc-z.abs_500p1.3 --sim-sign abs --overwrite --cwpvalthresh 0.25 the following error occurred Loading y from /Applications/freesurfer/subjects/average_IPS_FS7_Linux/stats/glm_group_n135/--perm-force error: mri_read(): couldn't determine type of file /Applications/freesurfer/subjects/average_IPS_FS7_Linux/stats/glm_group_n135/--perm-force ... done reading. ERROR: loading y /Applications/freesurfer/subjects/average_IPS_FS7_Linux/stats/glm_group_n135/--perm-force The entire output is shown below. I do not understand why after the —y option in the command reported by FS in the terminal, i.e. mri_glmfit --C IPS_2groups_n135_Thickness_LH.glmdir/tmp.mri_glmfit-sim-96372/IPS_2groups.mtx --sim mc-z 500 1.302 IPS_2groups_n135_Thickness_LH.glmdir/csd/lh_mc-z.abs_500p1.3.j001 --sim-sign abs --fwhm 14.598750 --fsgd IPS_2groups_n135_Thickness_LH.glmdir/y.fsgd dods --mask IPS_2groups_n135_Thickness_LH.glmdir/mask.mgh --y --perm-force --surf fsaverage lh white the input file (IPS_2groups_n135_lh_thickness.10.mgh) is missed and hence the following option —perm-force is interpreted as input file. How can I fix this problem?

RAM per CPU for running Freesurfer 7.1
by Ajay Kurani 14 Jul '21

14 Jul '21

External Email - Use Caution Hi Freesurfer Experts, I am designing some new hardware for a mini-cluster running Freesurfer and other neuroimaging toolboxes and wanted to better understand requirements from Freesurfer. 1) Is there a minimum amount of ram per core that is needed/recommended or is the amount of ram only defined per subject. Most of the threads I found say you need a minimum of 4 GB ram but these were from a long time ago and may not apply to the OPENMP code. Our compute node will have between 52-64 cores so I wanted to know what is the ratio for Ram to CPU (multithreading turned off) that is recommended as opposed to Ram per subject. 2) AMD vs Intel We will run jobs on an existing cluster that has Dual Intel Xeon 6230R and for our new minicluster we are debating between AMD and Intel. While AMD offers higher core-count per CPU, I am worried that results could potentially differ based on the CPU/underlying libraries. We plan on using docker images so from your perspective do you have a recommendation ? Best, Ajay

Average intensity from functional image within a label along the surface
by Erik Jahner 12 Jul '21

12 Jul '21

External Email - Use Caution I am interested in obtaining the average intensity within a label from each frame of a functional image that has been smoothed on the surface (I have generated the label). However, the functional connectivity pipeline seems to use only volume based seeds. It seems to me that in using the FreeSurfer software we would want to take advantage of the surface based smoothing and not return to getting the average of voxels in aparc+aseg. (1) Am I incorrect in my thinking here? (2) Is there a way to get the mean intensity of a label (I have created) at each frame along the surface to get a timcourse for a particular region? I see there is a way to do this with anatomical features such as thickness, but I do not see a way to do this with functional data across frames for signal intensity. Thanks ~Erik Jahner

Tracula 7.1.1 - trac-all - stat
by Fanny Noury 12 Jul '21

12 Jul '21

External Email - Use Caution Hello FreeSurfer Developers, I am just started to use "the trac-all -stat" command of Tracula 7.1.1 to reconstruct a mean tract for each pathway for all the subjects of a group. Several files are created for each pathway in the "stat" directory. What are the differences between these two files created for the AF, MD AD and RD diffusion parameters : - TRACTNAME_PP.avg33_mni_bbr.**.txt - TRACTNAME_PP.avg33_mni_bbr.**_Avg.txt Thank You very much for your help.

Re: [Freesurfer] mri_glmfit DOSS
by Dr. Cornelius Kronlage 12 Jul '21

12 Jul '21

External Email - Use Caution Thank you for your reply! Using DOSS is precisely what I was trying to do, but mri_glmfit doesn't let me. I worked around by creating the design matrix in matlab and specify it to mri_glmfit directly, but I was wondering whether this might be bug in the parsing of the FSGD file. As a minimal example to reproduce, see the attached file. Trying to run mri_glmfit (doesn't even need more input specified), I get: $ mri_glmfit --fsgd dosstest.fsgd doss gdfRead(): reading dosstest.fsgd INFO: DeMeanFlag keyword not found, DeMeaning will NOT be done. Continuous Variable Means (all subjects) 0 C 32.1111 8.50417 1 D 0.555556 0.496904 2 E 5.44444 3.49956 Class Size and Means of each Continuous Variable 1 A 1 50.0000 1.0000 4.0000 2 B 8 29.8750 0.5000 5.6250 ERROR: Class A has 1 members.
