To whom it may concern, 

I am writing a script in MATLAB to run an analysis in CONN toolbox, using BATCH commands. In there, I set up some commands to do the appropriate preprocessing steps:

BATCH.Setup.Preprocessing.overwrite='No';
BATCH.Setup.Preprocessing.done=1;
BATCH.Setup.Preprocessing.voxelsize_anat=0.8;
BATCH.Setup.Preprocessing.voxelsize_func=2;
BATCH.Setup.Preprocessing.fwhm=6;

When I try to run this script on a small subset of my real dataset, I keep getting the following error:

"Unable to perform assignment because dot indexing is not supported for variables of this type.

Error in Batch_all_subjects (line 46)
BATCH.Setup.Preprocessing.overwrite='No';"

If I then comment out line 46, the same error will repeat with the next line. 

I do not understand why this error would appear at this line, as I'm not even defining variables in this line. 
Any help would be much appreciated. 

Kind regards, 
Romke Hannema

Hi Romke

Could you please try adding the line:

   clear BATCH;

at the beginning of your script? (the error is likely a mismatch between some previously defined BATCH variable and the one you are trying to define now)

Dear Alfonso, 

Your suggestion is a good one, and one I thought of before. However, I already had it added into my script at the beginning of the file, before I posted my message. Would it be of any help if I posted the full script?

Kind regards,
