Hi,

I have downloaded the pestica_afni_v2 recently and wanted to try it with the run_pestica_ica.sh in the pestica_example folder where the program should work with the given epi_132vols.img and epi_mask.img. However, I get this error when the function prepare_ICA_decomp.m calls the BrikLoad.m function:

Warning:
Error in BrikLoad : HEAD file epi_132vols.img.HEAD not found

In ErrEval (line 107)
In BrikLoad (line 526)
In prepare_ICA_decomp (line 39)
Struct contents reference from a non-struct array object.
Error in prepare_ICA_decomp (line 40)
xdim=ainfo.DATASET_DIMENSIONS(1);

I am unable to find the problem and I hope I can get support on this forum

Best Regards

David
