This was done to clear up a misunderstanding when using a target subject other than fsaverage. The way that 5.3 worked is that the data were actually sampled onto fsaverage through the ?h.sphere.reg. The target subject was only used in the smoothing process (if you even specified that as part of mris_preproc). This gave people the impression that they were sampling their data onto the target subject. To replicate 5.3, just specify fsaverage as the target and proceed as normal using your target after those commands. If you want to sample onto your target subject, then you will have to register each individual subject to the target, eg,
surfreg --s individualsubject --t average_AN_FS6_long_split
This will create ?h.average_AN_FS6_long_split.sphere.reg which can then be used in mris_preproc

Dear FS experts
we are trying to run statistics in FS6 Linux. Everthing worked fine until we applied the command mris_preproc that called mri_surf2surf and produced the following error:

this line is odd:
MRISread(/usr/local/freesurfer/subjects/s1006_01.long.s1006_base/surf/rh.average_AN_FS6_long_split.sphere.reg): could not open file
we are wondering why FS6 introduced the name of the target average (average_AN_FS6_long_split) into the name of the individual subject (rh.average_AN_FS6_long_split.sphere.reg) when looking for s1006_01.long.s1006_base/surf/rh.sphere.reg.
When using FS5.3.0 mris_preproc worked without this error.
Any idea?
