Description
Hi.
I'm new in the physionet's web page. I'm very confuse because I don't know if the channel that I'm reading in matlab that's the right one.
I'm using the function "readedf" for the UCDDB data base signals. This fuction is used like this:
function [x,Fs,Start_date,Start_time,Label,Dimension,Coef,Nmb_chans,N] = readedf(fname,ch,t1,t2)
And I'm reading it :
[data, header] = READEDF('C:\NewUach\BCI\wfdb-app-toolbox-0-9-10\senales\ucddb002.rec',5)
The last argument is the channel's number, and I don't know if it's correct. I want to read the channel C3-A2 .
Please, help me. Thank you.

Research direction
Start with the READEDF call and the WFDB Toolbox documentation for its channel argument; inspect the returned header labels to determine how channel selection is represented. The payload names no repository file or test, so done would require a clear, verified usage explanation for selecting C3-A2 rather than a defined code change.
