read mcd file in Matlab

Post  Jenq-Wei on Thu Jul 30, 2009 11:34 pm

Hi,

I use matlab version7.7 (R2008b) to write program to access .mcd file.

I could read the .mcd file if I use MC_RACK version 3.5.8 to record data.

However, I can not read the .mcd file if I use USB-ME256-system and MC_RACK version 3.7.0 to record data.

I get the error information from matlab below.
??? Index exceeds matrix dimensions.
Error in ==> datastrm.datastrm at 353
d.ChannelID2{i}=d.sorterleft(tmpsort)';


Regards,

Jenq-Wei

Dear Jenq-Wei,

the datastrm.m file works for files recorded with a 128 channel systems but you will get an error message for files recorded with a 256 channel systems. We will fix the bug and send the corrected m file to you as soon as possible.

Kind regards,

Gerald

Dear Gerald,

Thank you for your reply.

The name of our institute is "Universitätsmedizin der Johannes Gutenberg-Universität

And the serial number of the USB-ME256-system is MEA256-0515374 (0006).

Have a nice day,

I am experiencing the same problem with the 256MEA. Could you also provide me with the revised .m file?

The Matlab interface with the MCStream.dll does not fully support our new
256-Mea-Systems. The reason is, that it was basically the reader for the Meatools
and there is no further development by the group in Freiburg.

However to make the Matlab interface run you need another sorterleft array. You find the arrays at the end of the post, but you should include it at the appropriate positions in datastrm.m yourself.

For new projects we recommend Neuroshare and sigTOOL or FIND. Please visit the download
section of our web page:
http://www.multichannelsystems.com/downloads
in the box data exports there is Neuroshare with some documentation where to find
the needed tools.

Kind regards, Jens
