External Email - Use Caution Hi there,
Thanks for the advice, I have followed these suggestions and used the fs_install_mcr command and can see the the libmwm* libraries are installed under $FREESURFER_HOME/MCRv97/bin/glnxa64. I also added the path the script suggested once finished to LD_LIBRARY_PATH. I’m now not sure how to open matlab now though as I can’t find any executable matlab file? There were no error with the command but it doesn’t look like matlab was installed… Thanks again for the help, Sophie Matis | Data Management & Research Officer School of Health Sciences & Brain and Mind Centre Faculty of Medicine and Health The University of Sydney Brain and Mind Centre, 94-100 Mallett Street, Camperdown (M02G) | The University of Sydney | NSW | 2006 sophie.ma...@sydney.edu.au<mailto:shona.brin...@sydney.edu.au> | sydney.edu.au<http://secure-web.cisco.com/1LNCVY-V_pCXtsh-3fvLILUg4Gjx2MpjNmpEjb8TT-p9PBtVnwf1Peehe1ltYAjzBqoU68lJHSp8uequwNAk3VBEVAFOWzLjbcTFewQlMlMOugkmkHbzYVEqceVA4zWw2iGhsVTz63kYUVTXvqlL61pdXh9twCFQMDBpOp7qpDsYM6mW4TaJ7sQ967zPbEraDTds7L-XhorbnYYiE1kKsDp83dbbxnte7R-3UwgS-V4tiZFgFSF4iO9b0v5Nz3YFGgnFQSHhvt2b9mmou5C40jfGyUQF3KEVUtrXQ3Ns_WKUemDzctLj5VFD3RnYT25CC/http%3A%2F%2Fsydney.edu.au%2F> CRICOS 00026A This email plus any attachments to it are confidential.

So I presume someone at your site installed R2023b separately via a Mathworks matlab installer. We do provide a script, fs_install_mcr, to install either the R2014b or R2019b matlab runtime environment into the freesurfer tree for use. I don't know if running R2019b would affect what you report below, but you could try it via the commands below. - R. $ export FREESURFER_HOME=/usr/local/freesurfer/7.4.1 <--- linux install path $ source $FREESURFER_HOME/SetUpFreeSurfer.sh <... output showing SUBJECTS_DIR and other environment variables> $ cd $FREESURFER_HOME/bin $ sudo FREESURFER_HOME=$FREESURFER_HOME ./fs_install_mcr R2019b I believe this sets things up so the libmwm* libraries are installed under $FREESURFER_HOME/MCRv97/bin/glnxa64. You can try adding that path (or any path the script output recommends) to the start of LD_LIBRARY_PATH. You should remove any other entries to a different MATLAB distribution.

For two groups I have been able to proceed through the steps fine and have my significance files which look normal. For the last group I am running into an error on the “[lhTh0,lhRe] = lme_mass_fit_EMinit(X,[1 2],Y,ni,lhcortex,3); “ step. MATLAB returns “Warning: Matrix is singular, close to singular or badly scaled” and lhTh0 and lhRe are created as matrices with only NaN values. Has anyone run into this error before or have any tips for troubleshooting it? I haven’t had any errors on the longitudinal processing steps and visual QC on my files looks normal. No errors on mris_preproc or mri_surf2surf. An aparcstats2table for thickness doesn’t reveal any NaNs.
