Error in task module

[ymstmshr]

Can't perform task module
I'm performing 'task' module to estimate brain activation but FEAT doesn't go well.

Thank you very much for your kind help, but I can't correct it yet.

In my 'real' directory, there are EV files like:
"/home/denbo5/ymm/projects/nf/data/BIDS/normal/derivatives/task/EVs/sub-NFB01/ses-s1/run-01/3BK.txt"

In a design.fsf that was created by the task module (/task/model/sub-NFB01_ses-s1_run-01_design.fsf),

# Custom EV file (EV 1)
set fmri(custom1) "/home/dcn/ymm/data/data/BIDS/normal/derivatives/task/EVs/sub-NFB01/ses-s1/run-01/3BK.txt"

I use the following singularity command

singularity run --cleanenv -B /home/denbo5/ymm/projects/nf:/home/dcn/ymm/data ${SIMG} \
	-c /home/dcn/ymm/data/analysis/code/XCP/normal/cohort/task_cohort_N15.csv.NFB01.csv \
	-d /home/dcn/ymm/data/analysis/code/XCP/normal/design/v1.0/task.dsn \
	-o /home/dcn/ymm/data/data/BIDS/normal/derivatives/task \
	-r /home/dcn/ymm/data

Could you tell me if there is anything wrong? Thanks!
