DPARSFA parallel pool error

Dear Chao-gan,

 Greetings!

 I am trying to use DPARSFA to run analyses. The first time I run, I got the following error message:

I simply restarted the program, loaded the settings using the saved .mat file, then I met a parallel working problem. Although I set the parallel workers as 0 in the GUI window , it  seems automatically assigned  8 parallel workers (eight subjects?).  Here is  what in matlab log:
 
Starting parallel pool (parpool) using the 'local' profile ... connected to 8 workers.
Analyzing and transferring files to the workers ...>> 
 
 It stayed at this stage for over 10 hours without actually doing any analysis further. Is it really running the analysis in the background? I didn't find any outputs at all which makes me doubt it is doing anything.  I am using matlab2014a. Any idea of possible problems? Many thanks for your insight. 
 
Another question is regarding the functional connectivity. In defining ROIs, is that okay to include a ROI (for example cingulate) overlapping with another ROI  (say anterior cingulate, a subregion of the cingulate)? In anther words, whether the ROIs input in your program have to be spatially independent or not? Does the program run each ROI connectivity with the rest voxels of the brain independently or use a GLM type of model? Thanks.
 

Forums:

Hi Lihong,

1. This is related to the conflict between SPM8/12 files and the spm5 files inside REST. For REST, please don't add with subfolders, just set path for the main folder is OK. 

2. Seems there is something wrong with your parallel computing toolbox. How about not do anything in setting "parallel workers"? The program will be running on only 1 worker.

3. They are independent bivariate correlations.

Best,

Chao-Gan

 Thank you for your quick response Chao-Gan! I still get some errors by leaving the parallel pool blank:

Warning: matlabpool will be removed in a future release.
Use parpool instead.

Warning: File: DPARSFA_run.m Line: 671 Column: 83
The temporary variable RefFile will be cleared at the beginning of each iteration of the parfor loop.
Any value assigned to it before the loop will be lost.  If RefFile is used before it is assigned in the parfor loop, a runtime error will occur.

The client lost connection to worker 6. This might be due to network problems, or the interactive communicating job might have errored.
 

Hi Lihong,

It seems a problem regarding to your matlab's parallel computing toolbox.

Just don't touch the edit box of "Paralle Workers", I think you can run on one worker.

Best,

Chao-Gan
