Re: [Freesurfer] -hires flag sometimes breaks recon-all

[Douglas N. Greve]

The -hires performs all operations in 0.7mm space whereas leaving it off 
causes recon-all to "conform" the volume so that it is 256^3 and 1mm^3. 
If you want more help with this, send the log file

Hi,

I have 7T MP2RAGE data of 25 individuals with an isotropic 0.7mm voxel 
resolution. I initially ran FS with the -hires flag to preserve the 
additional detail, but in 4 cases this crashed the process, while 
running the same image without the -hires flag works fine (surfaces 
visually inspected). I just wanted to know what could be the cause for 
this difference in behavior between the two options.


Many thanks in advance,
Chris
