[Erppcatoolkit-support] Channel issues?

[Andrew H. <and...@uc...>]

Hi Joe, and others,

I'm just starting to get into the EP Toolkit again, and trying to Preprocess an epoched .set file, using autoTemplate (or none) i'm getting the following error:

Error: The file /Users/andrew/Documents/Research/DATA/BFBBFB_EPOCHS/LER_meta/S101/101_BFB_1_LER.set is missing information on some of the channel locations needed.

This .set file has channel locations according to EEGLAB.. and I've installed all the necessary components in the EP instructions.. am I missing something?

My files have 32 (reduced from 64) channels, all using standard labels, though the "type" field is empty, and no "value" field exists.   

I created the epochs using ERPLAB instead of EEGLAB - is there a prob in the way ERPLAB binlister / pop_epochbin creates the epoched file's event structure as opposed to how EEGLAB does it?

Thanks,
Andrew


full output:

Warning: No 'value' field in the events structure.
EEGlab data files should have both a 'value' field
to denote the generic type of event, as in 'trigger', and a 'type' field
to denote the nature of this generic event, as in the condition of the experiment.
Note also that this is the reverse of the FieldTrip convention.
Read in 1 cell with a total of 601 trials.
The name of the experiment is: 
The pre-stimulus period of the data is: 599.6094 msec.
