I am trying to do a cross-sectional baseline analysis from the outputs of the longitudinal processing stream, following the advice on a previous question's thread:

From my reading of the issue, I need to run the following command, entering the cross-sectional title folder as the first input.

recon-all -long "subj_crossfolder" "subj_base" -qcache

For this step, i know it is necessary that recon-all knows where the cross folders are located, although from my understanding, it does not actually use data from these folders., instead using the data in the .long folders.

My issue is that I do not have access to the cross folders anymore, and was wondering if there was a work around to do the cross sectional analysis without them?

Thanks for any help!
