[FieldTrip] Question about loading in ERP data

[Amna Hyder]

Hi Julian,
Sorry I posted the wrong one - I get the same error when I use timelock as
the option

comp = eeglab2fieldtrip(ERP, 'timelock')
Reference to non-existent field 'icachansind'.

Error in eeglab2fieldtrip (line 54)
 header.label   = { tmpchanlocs(EEG.icachansind).labels };

Please let me know if you have any ideas on what could be going wrong.
