problem with the filtered data extracted from MC_RACK

Post  hourwork on Tue Mar 10, 2009 4:56 am

I'm trying to use the MEA_tools command (like this: V=getraw_uV(D, [0,100], 'make64','no', 'electrode', {'13'} ) to input the data which has been filtered in the MC_RACK (cutoff frequency:25Hz; High Pass), but failed. The error indicated as follow:
Index exceeds matrix dimensions.
Error in ==> getraw_uv>convertNewFileData at 308
duVchunk = ad2muvolt(D, d.data(cid,Smile,
'Electrode Raw Data');
Error in ==> getraw_uv at 100
duV(:,m:n) = convertNewFileData(D, d, cid,make64);

I once used the same command to input the raw data without filtering,there was no any problem. I checked the information of these two kind of datastream ( raw data and filtered data) and found some difference. In raw data, ZeroADValue and ZeroADValue2 are same, but they are different for the filtered data. does this cause the above errors,I'm looking forward to getting your help. Thanks!

Does the command still work with "Raw Electrode Data"?
The order of the channels is different in "Raw Electrode Data" compared to "Filtered Data".

You are right, the command still can work with 'Raw Electrode Data'. So I've changed some input parameters in the original matlab code, now it works. Thank you very much
