Thanks for the ideas. The -noextras option worked perfectly. The file was
processed only with mne_browse_raw, and I think all I did was add a
user-defined event at time 0 and change the filter options. The original
data file did have the STI channels (including 014), but the postprocessed
file didn't have any of those. Not sure what I did to remove it. In any
case, seems to be working well now, and there was no information in the
trigger channel anyway.
