Co-registration without ant resolution cost
by Salar Dini, Elaheh 07 Mar '22

07 Mar '22

External Email - Use Caution Dear Freesurfer developers, I have a dwi.nii image which I want to co-register on a orig.mgz (produced by running recon-all on the subject's T1 image) file without any drop in the quality of image (i.e. without any resolution cost, or changes in the acquired dwi intensity at each voxel). I was told that if you just translate the image and don't rotate it during co-registration, the quality of the image won't drop, because you don't cut through the existing voxels on the original image in resampling process to fit it in the destination image. Also, I'm not sure if the --no-resample flag in mri_vol2vol helps with that. Can you please guide me toward a better understanding of how co-registration affect the image quality? and ways to prevent that? Freesurfer version: 7.2 & the Platform in use: CentOS7 Thank you and all the best, Ela

fcseed with average data
by Marilena Wilding 07 Mar '22

07 Mar '22

External Email - Use Caution Dear FreeSurfers! I'm currently trying to do seed-based analysis. Therefore I'm using fcseed-config and fcseed-sess to configure my seed region. However, since I'm using a dataset that has been preprocessed with fMRIPrep, I'm having a lot of trouble doing this. Although I'm doing surface analyses, it seems that fcseed-sess is deriving the seed time course from the volumetric space (which of course makes sense since aparc+aseg is in volumetric space). I was wondering whether there is any way to use these functions with data, that has already been mapped onto the surface (i.e., fmcpr.sm0.fsaverage.lh)? The fMRIPrep output doesn't produce a template file, that seems to be indispensable for the formation of such a seed region. This is the code I used: fcseed-config -segid 1035 -fcname lh_insula_new.dat -fsd bold -mean -cfg mean.lh_insula_new.config -funcstem fmcpr.sm0.fsaverage.lh (I'm using funcstem since I don't have fmcpr.nii in my folders, only fmcpr.sm0.fsaverage.lh). fcseed-sess -sf sessid -cfg mean.lh_insula_new.config And this is my error: fcseed-sess -sf sessid -cfg mean.lh_insula_1010.config Logfile is /storage/marilena/freesurfer_data/Study_3/Excite_data_3/Project/log/fcseed-sess.lh_insula_1010.dat.log Mon 07 Mar 2022 01:24:38 PM UTC Linux pslg067035.pers.ad.uni-graz.at 5.4.0-100-generic #113-Ubuntu SMP Thu Feb 3 18:43:29 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux setenv SUBJECTS_DIR /storage/marilena/freesurfer_data/Study_3/Excite_data_3/Project/structural/ cd /storage/marilena/freesurfer_data/Study_3/Excite_data_3/Project /usr/local/freesurfer/fsfast/bin/fcseed-sess -sf sessid -cfg mean.lh_insula_1010.config freesurfer-linux-centos7_x86_64-7.1.0-20200511-813297b Mon 07 Mar 2022 01:24:38 PM UTC Linux pslg067035.pers.ad.uni-graz.at 5.4.0-100-generic #113-Ubuntu SMP Thu Feb 3 18:43:29 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux setenv SUBJECTS_DIR /storage/marilena/freesurfer_data/Study_3/Excite_data_3/Project/structural/ cd /storage/marilena/freesurfer_data/Study_3/Excite_data_3/Project /usr/local/freesurfer/fsfast/bin/fcseed-sess -sf sessid -cfg mean.lh_insula_1010.config freesurfer-linux-centos7_x86_64-7.1.0-20200511-813297b mri_label2vol --seg /storage/marilena/freesurfer_data/Study_3/Excite_data_3/Project/structural//01/mri/aparc+aseg.mgz --reg /storage/marilena/freesurfer_data/Study_3/Excite_data_3/Project/01/bold/001/register.dof6.lta --temp ERROR: could not determine file for /storage/marilena/freesurfer_data/Study_3/Excite_data_3/Project/01/bold/001/template --fillthresh .5 --o /storage/marilena/freesurfer_data/Study_3/Excite_data_3/Project/01/bold/001/tmp.fcseed-sess.470390/seg.nii.gz --pvf /storage/marilena/freesurfer_data/Study_3/Excite_data_3/Project/01/bold/001/tmp.fcseed-sess.470390/pvf.nii.gz ERROR: Option could unknown Thank you a lot in advance!!

Update on freeview error with M1 Macs running Monterey (MacOS 12.X)
by fsbuild 05 Mar '22

05 Mar '22

External Email - Use Caution Please check you have your freesurfer license file in a readable location, e.g., you can set the environment variable FS_LICENSE to point to the file license.txt in your home directory.  … in bash or zsh ...$ export FS_LICENSE=$HOME/license.txt… in csh or tcsh ...% setenv FS_LICENSE $HOME/license.txt The current development build of freesurfer now uses a newer version of the Qt distribution compared to the previous 7.2.0 and 7.1.1 releases.  You could try the development build to see if it remedies display issues with freeview on M1 Macs.. The package file  https://secure-web.cisco.com/1ZzEv2RHt0Q6Zowkpf2ipMDHM24zsuJwEJaPkN-sAc1WrZLf0pHDqrMdfHcwcLbdayl4GwciE3HSVe9hZ6mQiXeANHJpN--83bnCvOT7FTKOVmKgEurvQhXDpV-HLpvi7cy9mqEjbrM_QHH5YwMG_kxPyC9lM2wEFIgANTUhY1D78ULhUW3dmG3TLjm4OaYuVYHGjqEmJJD_VxOFIwA4suAJnq9KJ64uV-EQLOjZKIuS8imnZQmL6K9nd3ryadadTMaMdl7M87vojtuhub2Ub-P89vwRo_F2-DW6q4B4nhD_xSFSIMLZobD_0n84OPzF96jmVgKgNPDtsVf8YOoMydQ/https%3A%2F%2Fsurfer.nmr.mgh.harvard.edu%2Fpub%2Fdist%2Ffreesurfer%2Fdev%2Ffreesurfer-darwin-macOS-dev.pkg%26nbsp; will install the development freesurfer distribution as /Applications/freesurfer/dev.  It will not interfere with or clobber your pre-exiting freesurfer 7.X X distributions installed as /Applications/freesurfer/{7.2.0, 7.1.1}. To switch to running the development build, (re)set FREESURFER_HOME in a new terminal window to /Applications/freesurfer/dev and then source the usual script to setup the freesurfer environment, e.g., source $FREESURFER_HOME/{SetUpFreeSurfer.sh, SetUpFreeSurfer.csh} I’ve tested running the freesurfer development build on a 2019 Intel MacBook Pro running Monterey.  That laptop uses an AMD Radeon 5500M graphics card with 4 GB of memory to drive both the laptop display (3072 x 1920 with 24 bit color) and a 2nd monitor (2560 X 1600 with a framebuffer depth of 30 bits).   Neither of those display are 4K resolution.  But I have not seen any issues with freeview displaying graphics on that 2nd monitor with the Intel MacBook Pro running MacOS Monterey, BigSur or Catalina. To completely remove the development build and the package file download you can do,$ sudo bash /Applications/freesurfer/dev/uninstall.sh$ rm -f $HOME/Downloads/freesurfer-darwin-macOS-dev.pkg - R. P.S. There have been reports of 2nd monitors with 4K resolution connected via USB-C cables causing Mac laptops running Monterey and BigSur to crash.  My understanding is that error is from the Mac graphics hardware not detecting the resolution of the 2nd display through that connection.   Switching to a USB-C to HDMI monitor connection fixed the issue for some users.  But I would avoid using a USB-C to USB-C connection for a 2nd monitor with 4K resolution.

fspalm error
by Janina von der Gablentz 03 Mar '22

03 Mar '22

External Email - Use Caution Hi FreeSurfer community, I try to ues fspalm to correct multiple comparisons for a surface-based thickness analysis. Below is the code I use: python fspalm --glmdir Home/*/lh.group.glmdir --cft 1.3 --cwp .5 --onetail --name palm_onetail_1.3 --iters 1000 --2spaces The analysis starts successfully until runs "palm prep complete". Then it tries to run the generated matlab script. Matlab seems to start correctly. Afterwards I get the following error: Undefined function or variable 'palm', followed by this error: cannot find expected palm output "fsp_clustere_tstat_fewp_c1.mgz" . check for run_palm.m failures I guess there is a communication problem between the terminal and matlab/palm. Palm is included in the matlab path and I'am able to start palm within matlab. Any help with fixing this error would be appreciated. Thanks, Janina
