Hello FreeSurfer Developers,

 

I'm attempting to run recon-all using -use-gpu option in Mac Pro 5,1 with OS X 10.12.1.

I am using GTX980 rom-flashed edition, and it supports CUDA properly with other tools.

Current cuda version is 8.0, and cudadetect command works perfect.

  CUDA Driver Version:                           8.0

  CUDA Runtime Version:                          5.0

  CUDA Capability Major revision number:         5

  CUDA Capability Minor revision number:         2

  Total amount of global memory:                 4294770688 bytes

  Number of multiprocessors:                     16

  Number of cores:                               448

  Support host page-locked memory mapping:       Yes

  Compute mode:                                  Default (multiple host threads can use this device simultaneously)

 

However, when I run recon-all -all -s DEP030 -qcache -use-gpu,

 

I face repeatedly the error 

 

reading transform from transforms/talairach.m3z

ERROR: cannot find or read transforms/talairach.m3z

No such file or directory

 

I found it might be caused since talairach.m3z couldn’t created.

 

I also found an error above.

Cuda error: MRIconvolveKernelX failed! in file 'mriconvolve_cuda.cu' in line 536 : unspecified launch failure.

freeing gibbs priors...done.

average std[0] = 5.0

 

I also attach full log file too.

 

Thanks.
