[MINC-users] mnc2nii dumps core

[Yoshitaka KUMAKURA]

Dear Claude,

Thank you for your reply.

mnc2nii -version returns:

program: 1.4
libminc: 1.4
netcdf : 3.6.1 of Mar  5 2007 07:16:16 $

I tried to install minc 1.51, but no success. Is minc 1.4 too old? I am
ready to send you the minc file with a normal file from the same
scanner.

Best regards,
Yoshi Kumakura
