[Eeglablist] Help with importing data in MATLAB/biosig

[kostas/othon Hatzimpaloglou]

Dear Sir or Madam,

I am having difficulty understanding importing EEG data to the matlab
file (attached)/ the file is used to pre-proccesse EEG data. using the
Biosig plugin. I am having two individuals' data that the stages (sound
signal & response) of the experiment are in csv files and the measured data
from each electrode were saved in excel file (two excel files). The files
have different timestamps which gives me a harder task to understand how I
need to solve this problem. I am attaching also two file from the two
different formats. How I can use them to be read by the eegpreproc.m script.

I am attaching the files to show the timestamp incoherence.and the MATLAB
script

Kind regards,
