[Eeglablist] Problem with STUDY - Precompute channel measures

[Cedric Cannard]

Hi,

Can you be more specific? Which measure and which parameters? ERP (removing baseline or not), Power spectra (FFT, PSD), etc. I remember having a similar issue recently when trying to compute PSD but no when selecting FFT. 

Maybe Arno can give some feedback. Otherwise, you can submit an issue on github: https://urldefense.com/v3/__https://github.com/sccn/eeglab/issues__;!!Mih3wA!E2jw1PpwwVb9zm7_HsAvxv53eDBS6cGfsGcVPTskKIYtTyPH79L6onNXbhIOEol3e1J70VbtqywcCdr_uSWB6E7_qQ$

After epoching, I merged the two files for LIMO but, in some ways, this is causing problems to STUDY. Unfortunately, I don't get any error from Matlab to report, but when I precompute channel measures (erp) it gets stuck for hours. I've tried even using just 2 or 3 participants and it does the same. I was wondering whether there is something wrong with my epoched and merged files. I am not sure if any of you has experienced some like this. I'm more than happy to share few .set files if necessary.
