appenddata: correction to question appenddata

[Ingrid Nieuwenhuis]

It doesn't matter if it are different datasets/headerfiles you can just
concatenate. But keep in mind that if the different datasets are measured in
different sessions, and the electrodes (when EEG) or sensors/headposition
(when MEG) is different in the two datasets, the same channel in the
concatenated dataset can measure a different brain area.

Sorry, for the error in the earlier email, dataset and headerfile are also
different (same subject). trialdef and datatype are the same.

so to restate the question,

The usage for appenddata is
data = appenddata(cfg,data1,data2,data3)

I can see that appenddata does look for cfg.trl etc. If I have cfg1, cfg2,
cfg3,  corresponding to data1, data2, data3, where cfg.dataset,
cfg.headerfile,
and cfg.trl are different, but cfg.datatype (continous) and cfg.trialdef are

the same,  will
data = appenddata(cfg1,data1,data2,data3) work correctly?

Hello,

The usage for appenddata is
data = appenddata(cfg,data1,data2,data3)

I can see that appenddata does look for cfg.trl etc. If I have cfg1, cfg2,
cfg3,  corresponding to data1, data2, data3, where dataset, headerfile,
datatype and trialdef are the same and the only difference is ofcourse in
the
.trl field, will
data = appenddata(cfg1,data1,data2,data3) work correctly?

Thanks for your reply,
sameer
