Dear CONN experts,

I want to analyze some almost raw data, so I only performed the realignment, coregister, and spatial smoothing in SPM before insert the data in CONN fields. It may seem strange but I don't want to perform the denoising to get the access to the first-level analysis, so I did not put any confounds to improve the original data, chose no detrending and wrote [0 Inf] in band-pass filter. I know I'm gonna get very noise data, but that's intentional.
However, in the 3rd step of denoising, I got this error message:

ERROR DESCRIPTION:

Error using conn_process (line 877)

Could someone please show me what's wrong and tell me how to skip the denoising step?
Thanks in advance!
