Troubleshooting Multi-Slice Volume Loading Issues in NRRD Files

Question

What's wrong with this NRRD file? When loading a single slice, it works correctly, but when loading multiple slices to generate a volume, it fails to load. The file is:

NRRD0004
# Complete NRRD file format specification at:
# http://teem.sourceforge.net/nrrd/format.html
type: short
dimension: 3
space: left-posterior-superior

Answer 1

Linked spec says:

3. data file: LIST [<subdim>]

Textual description says LIST is to be taken literally. So you should write that literally.

3. There are multiple detached data files, and their filenames are given explicitly, in the NRRD header, one filename per line, in the line starting after data file field specification, until the end of file. Thus, this form of the field specification must be the last specification of the header. If you have a single detached datafile whose name is unfortunate enough to be "LIST", you can still refer to it by "data file: ./LIST".

I would suggest this:

data file: LIST
I0023679.M01
I0023679.M02
I0023679.M03
I0023679.M04
I0023679.M05
I0023679.M06
I0023679.M07
I0023679.M08
I0023679.M09
