Dear experts in NeuroImaging,
I hope to find some recommendations using this helpful and vital forum.
I am trying to build a customized atlas using the atlases implemented in FSL (e.g. MNI atlas). Using the command
fslmerge -t <output> <input files>
this is working quite well.
However, I would love to build the atlas with several ROIs resulting in only one volume (4th dimension in the 4d file) instead of multiple merged files. In other software tools I recognized that this is possible. Examples are for example the aal90 atlas. All regions in the aal atlas are included in only one volume. This has some advantages I would like to benefit of as that using scripts all volumetric informations are in one single txt-output file instead of multiple files.
Any suggestions would be wonderful :)
Best, Andrea
