thanks Dr. Fischl,
Would there be a reason as to why recon-all crashed when doing the conformation then? I got the following error in my terminal:
Original Data has (0.5, 0.5, 0.5) mm size and (394, 466, 378) voxels. Data is conformed to 1 mm size and 256 voxels for all directions changing data type from short to uchar (noscale = 0)...

Hi Trisanna
you can use the -cm flag, but typically what we do is let recon-all "conform" the data to 1mm, then do a post-hoc surface deformation with the original highres data using mris_make_surfaces

Hi there
My initial email didn't seem to have sent and so I am re-sending it:
I would like to know if it is possible to create surfaces from a scan
that
is 0.5mm isotropic. I tried to run recon-all on our MNI 2009b atlas
which is
0.5mm cubed and it crashed quite quickly afterwards. I wonder if this
has to
do with the fact that Freesurfer tried to conform it to 1mm isotropic?
When I ran recon-all on the 1mm atlas it created some nice surfaces.
Let me know if you would like the .log as I cannot seem to make much
sense
of it.
best wishes
