Dear Alfonso,

I am running in CONN with a dataset of 42 subjects (2 groups of 21) in 1 session and 2 conditions (subvocal speech and finger tapping). The analysis runs over a external memory which still has 1619.6Gb  of free space (format: NTFS).

After running smoothly the preprocessing and denoising steps, I have gotten to the first-level analysis step. It run for a couple of hours without problems (over 15 hours pipeline was expected) but it stopped somewhere at the subject20_condition1_source155.

I decided to eliminate the 1st level results and repeat it again, and the same error was shown at "D:\conn\conn_project_t1_42\results\firstlevel\SBC_01\corr_Subject010_Condition002_Source155.nii".

Could you help me out here?


I copy the error description from the conn toolbox  log and from Matlab log:
