Reading source surface reg /Data/48/MRI_sMRI_fs_reconall_fs_reconall_gcv6s/surf/lh.fsaverage6.sphere.reg

No such file or directory

I guess it's because the naming of the sphere file is now different compared to v.5.3 (it was sufficient to run recon-all with the additional -qcache -target fsaverage6 flag), so it can't be found by mri_surf2surf. I tried to run mris_preproc instead of recon-all but I still get the same error. Could you please help me with the right command?

Thank you very much in advance!
