The file format for the waveguard cap used in the HCP is slightly different from previous ANT *.elc file formats, hence the reading functinos have to be updated.

@Abbas, can you please confirm that this file was written with software from ANT? It looks so, but is quite different from previous versions of the *.elc file format. -------------- ;EEG Channel Configuration ;Ant-Neuro Waveguard EEG cap NumberOfChannels=64 ReferenceChannel=Cz UnitPosition=mm ;(x,y,z) positions of EEG channels are in MNI coordinate ;Each entry: E=,x position,y position,z position ;Fields are delimited by commas, some fields might be omited (empty).

I have added a test script mbp> svn commit test_bug1785.m Adding test_bug1785.m Transmitting file data . Committed revision 6769. The test case for the new file is still commented out, as it fails.

remove trailing '=' when parsing *.elc files. mbp> svn commit private/ Sending private/read_asa.m Sending private/read_asa_elc.m Transmitting file data .. Committed revision 6770.

As you know, the *.elc format does not contain any additional comments, for example specifying the Reference channel, thus, I did not use this format. The EEG config file is based on *.vhdr format of BrainVision but I did not use exactly same format. Best, Abbas

(In reply to comment #4) Then the bug is not valid and nothing needs to be fixed. mbp> svn commit test_bug1785.m Sending test_bug1785.m Transmitting file data . Committed revision 6775.
