Because I am using data that was already preprocessed, I only need to do reconstruction. However, I realized that when I ran it, the error code, FreeSurfer data is required to make HSVS 5tt image. popped up.
Because I did not use FreeSurfer for preprocessing, I do not know what files freesurfer gives and hence do not know which files have to be inside of the freesurfer directory in order to make the reconstruction work… Does anyone know what kind of data I need and how I can get it?
Yes, there is very specific folder and file naming conventions. It would not be worth the effort trying to make it manually based on files you may or may not have.
Yes, you can add --do-reconall to your qsiprep command.
Our group usually runs freesurfer as part of fmriprep and then uses its output for the 5tt hsvs workflow in qsiprep. Almost any normal run of recon-all will produce everything you need for 5tt hsvs
