Is there a way to calculate the power spectrum for a timeseries saved in a
text file (like taken from the a design.mat file) within matlab?
As far a I understand, fslpspec does not take text files as input.
One alternative might therefore be to first write the ascii data into a
nifti file, but i couldn't find an easy way to do this.
I would appreciate any sugestion about how to
- run a util like fslpspec on text data or
- get the data from a text file into a nifti file.
(I am aware that one could use the 1dfft program in afni, or simply matlab.
But I'd prefer to use only fsl tools/utils, if possible.)
Thanks in advance!
