I’m new to brainstorm and have been looking for a way to do this but haven’t been able to.
I have a raw file for which I’ve estimated the source model and from the sources I’ve set event markers based on vector activation.
I also have other markers that relate to the stims being sent to the person in the MEG (TTL spikes).
Now I want to import my raw file into the database and set my epochs to correspond to the vector activation event markers, but I ALSO need to keep the TTL markers there as they were in the continous raw file (so if some events end up in the chunk that is imported as an epoch, i need them to be in the same place in that epoch).
Is there a way to do this? If not, is the order with which I’m setting my markers (and importing) wrong? Do I need to import my raw file earlier on, as a continuous non-epoched file and then set my markers on that? Please note that I absolutely need to set the TTL markers BEFORE epoching, because the way I set those markers requires a continuous timeline to match the timeline I have in my stim values text file. Once the file is split up into discontinuous epochs, I can no longer know which marker is which…
When you import you import your epochs from the continuous file to the database, the epochs should contain ALL the other events that happen during this epoch.
This feature has been added in April 2013: http://neuroimage.usc.edu/brainstorm/News#April_2013
Are your additional markers not visible in the imported epochs?
Please post some screen captures to illustrate your problem.
I just used one of the sample projects (sample_raw) from the brainstorm website, and added two events “test” and test1" just to make sure it wasnt the default events that were already in the project causing the problem.
Then after i import and select epoch by event, and i select all the events, if i click on any trial I do not see any events in the record tab.
Just close the file viewer after you add the new events to ensure that the modifications are saved.
Or use the menu File > Save modifications in the Record tab.
SOLVED: Thanks again for your input, but it did not solve my problem…it seems my instance of brainstorm was having a bug whereby it no longer displayed events in the records tab (anywhere), and only had the markers when I opened up a timeline. I just restarted brainstorm and then the feature worked properly. Thanks again!
