using BioSemi GSR data #8

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
the BioSemi application has no specific setting to record just the auxiliary 
signals (in my case, GSR data). I tried recording 32 blanks + aux channels, but 
in my c++ code I have access to 57 channels and in the xdf file (recorder with 
labrecorder) I have acess to 128. Problem is I cannot check which one of those 
correspond to the ones that I want, related to the GSR. Using BioSemi native's 
application, I can record it as the 41st channel.

What steps will reproduce the problem?
1. use BioSemi Active II amplifier to record GSR signals
2. Save them with lab recorder
3. analyse the xdf file in comparisson to the real time data obtained in c++

What is the expected output? What do you see instead?
The Number of channels vary and I cannot find the corresponding channel

What version of the product are you using? On what operating system?
windows 7, 32 bits
lsl 1.030

Please provide any additional information below.

Thank You

Daniel

upon reading the data files, The waves from channels 41~57 seem to be square 
waves, with small variations in the straight parts. This is not what is 
expected from a GSR reading, and reading it straight with BioSemi native 
application, I get meaningful data.
