Hello SPMers, I have just started to look into preprocessing and analyzing my EEG data with SPM8. But I ran into a problem in the first step. I use Neuroscan SynAmp2 64 channel EEG acquisition system. When I try to convert the .CNT file into SPM, it reads the file with twice as many time points, but the number of event markers seems to be OK, but now ISI looks like 5sec, while originally my ISI is 2sec. The EEG output also seems to be convoluted as well. After searching on the mailing I found out that changing S.inputformat = []; to S.inputformat = 'ns_cnt32'; in spm_eeg_convert.m will probably solve the problem. It sort of did, the EEG output looked more EEG like (however, I don't know of a way to check if it indeed was converted correctly, does anyone?), and the file duration (start to finish) also seems to be fine, but now I see only about half as many event markers as there are in the original file and the ISI still seems to be 5sec. I don't know exactly what is going on, and what am I doing wrong here. Any help will be much appreciated. Thanks -Muhammad
