[Eeglablist] making one .set out of two ".sets"

[ida miokovic]

Dear Makoto,

both of my data sets are given in paired files (set1.set; set1.fdt and
set2.set; set2.fdt), so what would be the procedure of preparing them in
way that I can operate with them in way you suggested?

I tried loading first data set into eeglab, and the put its values into one
variable:
>> variable.data(1:120,:)=EEG.data(1:120,:);
Then I loaded second data set into eeglab and put its values into the same
variable:
>> variable.data(121,:)=EEG.data(121,:);
onto 121st position (variable and EEGs are in struct format)
Then I saved variable with save ('variable'), and then changed its format
from .mat to .set.

When loading variable.set into matlab I obtain only second data set (1
channel)...I am obviously missing something, though your procedure is 100%
clear to me.

Thank you very much

Ida
