[Homer-users] batch processing of stimulus marks

[Perdue, Katherine]

Hi Darragh,

Do you want to add stimulus marks, or some sort of behavioral measure that goes along with the marks? The stimulus marks themselves should be in the “s” variable of the .nirs file, and any information that goes along with the stims can be put into a “userdata” structure which is a cell. The first column should be the stimulus time in seconds, and any additional columns are whatever behavioral or other data you want to include.

best,
Katherine

Hi,
Sorry if this is an obvious question as I’m new to fNIRS having come from a MRI background. I have a lot of nirs data on cognitive tasks and need to compare multiple conditions across patients and healthy volunteers. I can add the stim marks in the stimGUI individually for each file but this is very time consuming considering I have over 100 files in which to specify conditions. Is there a faster way, for instance applying a batch process, or applying the stimGUI to multiple files in a dataset?
Thanks
Darragh
