Dear Freesurfer experts,

I'm trying to run mri_vol2vol on a functional mri to resample it onto orig.mgz. I get this error:

```

mri_vol2vol(98217,0xa0ce01d4) malloc: *** mach_vm_map(size=262144) failed (error code=3)

*** error: can't allocate region

*** set a breakpoint in malloc_error_break to debug

MRIalloc(256, 256, 256): could not allocate 262144 bytes for 13664th slice

Cannot allocate memory

```

I was wondering if you have any suggestions. Thanks in advance for your time.

Best,

Ehsan.
