<div dir="ltr"><div>Hi, everyone! I am trying to create a cortical sheet source model from the standard colin27 brain with accompanying DKT atlas for EEG source reconstruction (single_subj.nii in Fieldtrip template directory). After doing recon-all in FreeSurfer, the resulting meshes are far too large ~160k vertices per hemisphere which is taking too long to run the source analysis on. I followed the instructions according to this tutorial (<a href="https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.fieldtriptoolbox.org%2Ftutorial%2Fsource%2Fsourcemodel%2F&data=05%7C02%7Cfieldtrip%40science.ru.nl%7C95dfd5f11eba45cd573208dd8e357ca4%7C084578d9400d4a5aa7c7e76ca47af400%7C1%7C0%7C638823082693304411%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C60000%7C%7C%7C&sdata=%2BZ%2Fuj6NFO7y8Lj7DEfksyqReRs%2FbT9YPXqYfpCPhMX8%3D&reserved=0" originalSrc="https://www.fieldtriptoolbox.org/tutorial/source/sourcemodel/">https://www.fieldtriptoolbox.org/tutorial/source/sourcemodel/</a>) and set up the HCP-Workbench and copied the requested directory contents to a common folder to use ft_postfreesurferscript.sh to make the lower resolution cortical meshes.</div><div><br></div><div>While I can get the script to run, I am facing the output and error copied below. If there is any other information I should provide please let me know. I am confused about this output because it looks like the error file is one that should be created by the script however it is not found. I would greatly appreciate any insight on how to fix this.:</div><div><br></div><div>Command</div><div>--------------</div><div>/mnt/c/Users/mjame/Documents/MATLAB/fieldtrip-20240504/bin/ft_postfreesurferscript.sh /usr/local/freesurfer/7.4.1/subjects single_subj /usr/local/freesurfer/7.4.1/subjects/workbench_freesurfer</div><div><br></div><div>Output & Error</div><div>--------------------</div><div>START: FS2CaretConvertRegisterNonlinear<br>Saving /usr/local/freesurfer/7.4.1/subjects/single_subj/workbench/single_subj.L.white.native.surf.gii as a surface in TKREGISTER space<br>Saving /usr/local/freesurfer/7.4.1/subjects/single_subj/workbench/single_subj.L.pial.native.surf.gii as a surface in TKREGISTER space<br>Saving /usr/local/freesurfer/7.4.1/subjects/single_subj/workbench/single_subj.L.sphere.reg.native.surf.gii as a surface in TKREGISTER space<br>Saving /usr/local/freesurfer/7.4.1/subjects/single_subj/workbench/single_subj.L.sphere.native.surf.gii as a surface in TKREGISTER space<br><br>While running:<br>wb_command -set-structure /usr/local/freesurfer/7.4.1/subjects/single_subj/workbench/single_subj.L.sulc.native.shape.gii CORTEX_LEFT<br><br>ERROR: NAME OF FILE: single_subj.L.sulc.native.shape.gii<br>PATH TO FILE: /usr/local/freesurfer/7.4.1/subjects/single_subj/workbench<br><br>File does not exist.</div><div><br></div><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div style="border:0px;font-stretch:inherit;line-height:inherit;margin:0px;padding:0px;vertical-align:baseline;color:rgb(0,0,0)"><font face="arial, sans-serif">Thanks,</font></div><div style="border:0px;font-stretch:inherit;line-height:inherit;margin:0px;padding:0px;vertical-align:baseline;color:rgb(0,0,0)"><font face="arial, sans-serif">Michael</font></div></div></div></div></div>
