crash on load #46
Description
Hi, I am excited to get started on BrainBay. I have a sleep study from a local hospital I want to use as data. It crashes when I try to load it in the EDF reader, although it loads fine in other EDF readers (they cannot do what BrainBay does unfortunately). I am using BrainBay 2.8.1 on an up-to-date win 10 machine. The sleep lab itself uses NATUS software, which I do not have access to. I ran an EDF/EDF+ checker in Polyman and it passed with zero fails and 42 warnings with some clipped signals. That report is below in the code block. Is there any way I can get this to load> I do not think it is a memory problem, since I have 64 gigs of RAM and the file is 1.7 gigs. When I add source => EDF reader and click the open file dialog and choose the EDF file, it clears the open file dialog, pauses for a few seconds like the file is loading, and then crashes. I can put the EDF file up somewhere if that helps. Demo files load fine. Any guidance you can give me is appreciated, I'd really like to get this working. Thanks. edit: attached bbay.log
