Hi,

I'm appealing to the vast knowledgebase on this forum to help me find a simple way to do the following. I've got a full surface dataset (in niml format) in which a long timeseries (2000+ timepoints) is mapped to each node. I'm trying to cherrypick certain timepoints for a subset of nodes and put it into a 1D file for reading into MATLAB.

What I've got is:
-a niml format ROI dset mask indicating which nodes I care about
-a 1D file specifying which timepionts I'd like to grab from said nodes (all zeros with ones at timepoints I care about)

What I'd like is an output file (to be read into MATLAB) in which:
-each column represents a successive node (from the mask)
-each row is a successive timepoint value from the set specified in the 1D file

I think I can use ConvertDset to write out the columns/rows the way I want, but I'm not sure how to specify individual timepoints from a file of zeros and ones.

Thanks for any suggestions,
Adam
