Hi Salma,

I think mri_surf2surf was complaining /Users/salmasalhi/my_code/HumanBrain_v2/reconall/fsaverage/label/lh.glasser.annot. Can you check if the file exists?

The reason for "ERROR: could not determine type of lh.orig" is that mri_info doesn't handle surface file.

Best,

Yujing

External Email - Use Caution Hello FreeSurfer Developers,

I am trying to run the mri_surf2surf command as shown in this MRtrix tutorial on page 35 (MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://osf.io/pm9ba/https://secure-web.cisco.com/1IRfOd9DbtoZ73ePUy1kNxDjehQaayodvb_Pq3LttY1M2YqbKQhQ1UWIVGQmivIOeHqfZlJkiIPiENR9fGdSkObi00qtpoSZ8Jm9wwwQnxRhQm6hmGs6MvMportB8LLrr13nsIVJlGNgmDmVt2i_k6NqxieH97jsKyaWkKiulCv5J5ZWicVbSHhRfriTWUMfd88okHhuEhZqcDvEV0Hjlj2dOCZkdDjAYskYfmLgKCfunXsyywJZzs5SXHSYMHohUoO6chopWkH8GfYpBIEEGnVOaE9SeVAYRJWq1-wdIYO-YuJdIiLvOpah94FyrtBHuRNt0RS9IJYxQp6dPlEh5pw/https%3A%2F%2Fosf.io%2Fpm9ba%2F) in order to map the annotation files of the HCP MMP 1.0 atlas. I keep running into a "No such file or directory" error when the code tries to read the "lh.orig" file, but the file is clearly in the required directory. Below is the output of my code:

If I cd into the surf directory and check the files, this is the output:

The "lh.orig" file is clearly in the right place. I tried to check the format of the file by typing mri_info lh.orig but the output was "ERROR: could not determine type of lh.orig".

Below are more details about my setup: 1) FreeSurfer version: freesurfer-darwin-macOS-7.2.0 2) Platform: macOS Monterey 12.3.1 (M1 chip)

Thank you very much for your help, I greatly appreciate it.
