Ah, I see. Um. Well, at the time of that publication, mris_preproc had a bug in that it was actually sampling onto fsaverage and not truly the target subject (though it was smoothing on the target subject). So, in version 6, I changed it to sample to the target subject by requiring that the input subject be registered to the target. For fsaverage, this is done as part of recon-all. Since you have your own average, you will need to do it yourself with
surfreg --s subject --t average
for each subject (probably 1-2 hours per subject). Then when you run mris_preproc, it should find that registration and run properly. Now, having said all that, it was probably an incomplete conclusion from the paper that a custom template is needed, so I don't know if you need to do it or not. Probably makes it easier to publish to just do it the way in the paper.

Hi Douglas, Because the Jove article recommends using a study-specific template (cited the article in the original post) and our analyses is being run on an adolescent sample. Therefore, "average" corresponds to the average template for our current sample. Let me know if you have any other questions!

Why are you specifying the target as average instead of fsaverage?

Hello, I am running into an error while running the LGI analyses using FreeSurfer 6.0 following Jove article recommendations ( https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3369773/). The error is occuring when I try to run the following command:
mris_preproc --fsgd FSGD.txt --target average --hemi lh --meas pial_lgi --out lh.lgi.mgh
Here is the error message:

Of note, this command works fine when substituting the fsaverage rather than study average template, however this is an adolescent sample so we are not able to use the fsaverage. Any help would be greatly appreciated!
