[FieldTrip] ft_rejectvisual reduces trial length

[Eelke Spaak]

Hi Tineke,

That sounds like a bug to me. You could consider filing it:
https://github.com/fieldtrip/fieldtrip/issues

Meanwhile, as a workaround, I usually ensure that one of the columns
of my data.trialinfo contains unique trial identifiers (e.g.
data.trialinfo(:,end+1) = 1:numel(data.trial);). Then, after datclean
= ft_rejectvisual(cfg, data), the datclean.trialinfo(:,end) will
contain those trial IDs that are kept. Store those IDs somewhere and
then you can select the appropriate trials from the original data
using ft_selectdata.

Hope that helps,
Eelke
