I have discovered Brainstorm relatively recently and I love it so much, I am considering switching over to this for some of our lab's main data processing tasks. However, I am encountering one seemingly small obstacle that I would be grateful if anyone can help with.
For our laboratory an important goal is to be able to quickly "score" sleep stages in long, continuous recordings of sleep EEG. This basically consists of labeling consecutive 30sec epochs with event markers representing sleep stage, based on visual inspection. Brainstorm's existing functions are already well-suited for this, except for one problem: When scrolling through a raw file, there is a small overlap of data from one screen to the next. For example, when paging forward using F3 with page duration set to 30sec, the next screen displayed overlaps with the prior screen by a small amount (10%). This creates a problem for the otherwise simple goal of quickly and efficiently scrolling through epochs on an exactly 30-sec basis, which is required for accurate sleep staging.
So my question is, is there a way to set the page overlap amount to 0% while reviewing raw files? I have not been able to find any such setting in the GUI. I had thought of first segmenting the continuous data into 30sec epochs and then scrolling through epochs, but it is then a problem that one cannot then efficiently export all markers from all epochs as a single file.
Thanks so much for your help!
