mincException when trying factory.volumeLikeFile with 4D file.

[sulantha2006]

Hi, I am trying to write a 4D file using a reference 4D file. However, I am getting a mincException with no details. I believe it is an issue with the header of the 4D file. I will attach the reference file here.

Error:

Hi,

Can you provide a reproducible code example which triggers the problem. Thanks!

[sulantha2006]

h = fc.volumeLikeFile('A1795dynres_nlinatlas.mnc', '4dWrite.mnc')
This line triggers the problem. I attached a link to the reference file in the original issue.

Hi,

Can you provide a complete reproducible example?

[sulantha2006]

import pyminc.volumes.factory as fc
h = fc.volumeLikeFile('A1795dynres_nlinatlas.mnc', '4dWrite.mnc')

This code is complete and it produces the error.

Hi,

This appears to be NOTABUG with pyminc, but rather with minc-toolkit.

I just tried with pyminc/0.47 and minc-toolkit-v2 HEAD of the devel branch.
