[Eeglablist] right 'nopoint' option for pop_select?

[Andreas Widmann]

Hi Mauricio,

> could you paste the rest of the error message?

The rest of the error message is essential :) The problem is not in pop_select or your syntax, there appears to be a problem with the event structure in your dataset. Your dataset does not pass eeg_checkset, which is used by pop_select/eeg_eegrej to check conformity of the dataset.

Do you possibly have numerical values in the type field of your event structure (should be strings)? Probably, easiest is to check your dataset directly with eeg_checkset to find the source of the problem. Provide an as small as possible sample file (download link) demonstrating the problem if you can not solve it.

Best,
Andreas
