Hello Dr. Spielberg and colleagues,

I was interested in using GTG for just pre-processing (a colleague has a novel network detection algorithm I was trying to use). Would that be possible in GTG? I tried to input a resting state scan and a whole brain mask (for both the whole brain mask and ROI mask). I however ran into some errors. 

After clicking the preprocess button, I enter a vector for participant ID (Subjects={'2011031012401','2011031012401_rest.nii.gz'};), ROI labels (Mask={'WholeBrain','2011031012401_rest_mask.nii.gz'};), change the # of slices and TR, and select the appropriate files. I next click motion censoring (just for my piloting). I however get the following error:

>> METAlab_GTG
Warning: matlabpool will be removed in a future release.
To query the size of an already started parallel pool, query the 'NumWorkers' property of the pool.
To check if a pool is already started use 'isempty(gcp('nocreate'))'.

I'm using Matlab2014b; any thoughts on what I might have done wrong?
Any suggestions are greatly appreciated! I attached my preprocessing log (which says I'm missing files for the participant, but that file exist, etc.). Does GTG want individual (non-stacked/indexed) files?

Thanks much!
Jamie.
