Hello Matlab experts,
I am trying to subtract 6 secs off of the onset times that I have extracted from an excel file. I now have a series of vectors with the onset times (just a column of numbers) saved in .mat files. I am running into an Error: Undefined operator '-' for input arguments of type 'cell'. I just used the following code:
neutral_cue_onset_time_adjusted=neutral_cue_onset_time-6;
save ('neutral_cue_onset_time_adjusted.mat', 'neutral_cue_onset_time_adjusted');
The previous code I used to find and extract onset times was:
[num,txt,raw] = xlsread ('Placebo_MID_Reward_PLAEGO002_session1_Neutral.xlsx');
cue_type=raw(:,7);
cue_block_onset=raw(:,9);
neutral_index=find(strcmp(cue_type(:),'neutral'));
neutral_cue_onset_time=cue_block_onset(neutral_index);
save ('neutral_cue_onset_time.mat', 'neutral_cue_onset_time');
I would appreciate any guidance!
Emily
