[FieldTrip] importing large edf data

[Leila Ayoubian]

Thanks Steve:Thanks. You are absolutely right. However what I need to get is one more information added to this 
        2005           9          15          10          18          42

Which is milli second. so I need to have an output of let's say (which 222 is in milli second)
        2005           9          15          10          18          42        222

Do you know how I could do that?

Hi Leila (and Arjen):

I just tried this out with a sample file, it looks like you can get this information if you use ft_read_header() rather than ft_preprocessing. The cfg structure I got from ft_preprocessing didn't contain the time-of-day information, but the structure returned from ft_read_header did:

>> hdr = ft_read_header( cfg.dataset ); hdr.orig.T0

ans =

        2005           9          15          10          18          42



I assume that's showing year, month, day, hour, minute (presumably based on the clock of the computer that made the recording).

Best,
Steve

Thanks.I need to retrieve the time when the recordings occure and I don't see it. I get the Fs but no more.I am using this code :
cfg = [];cfg.trl = [1 1000000 0];%cfg.trl = [100001 2000000 0];%cfg.trialdef.triallength = 5;cfg.dataset =fileName; %'For leila.edf';cfg= ft_definetrial( cfg );cfg.continuous = 'yes';
datastr = ft_preprocessing(cfg);data=datastr.trial{1,1};chanls=datastr.label;Fs=datastr.fsample;
and getting this?datastr =?
? ? ? ? ? ?hdr: [1x1 struct]? ? ? ? ?label: {65x1 cell}? ? ? ? ? time: {[1x1000000 double]}? ? ? ? ?trial: {[65x1000000 double]}? ? ? ?fsample: 1024? ? sampleinfo: [1 1000000]? ? ? ? ? ?cfg: [1x1 struct]

cfg =?
? ? ? ? ? ? ? ? ? trl: [1 1000000 0]? ? ? ? ? ? ? dataset: 'Event13_Seizure_triggered_by_cortical_stim_Segment_1.edf'? ? ? ? ? trackconfig: 'off'? ? ? ? ? checkconfig: 'loose'? ? ? ? ? ? checksize: 100000? ? ? ? ?showcallinfo: 'yes'? ? ? ? ? ? ? ? debug: 'no'? ? outputfilepresent: 'overwrite'? ? ? ? trackcallinfo: 'yes'? ? ? ? trackdatainfo: 'no'? ? ? ? ? ? ?callinfo: [1x1 struct]? ? ? ? ? ? ? version: [1x1 struct]? ? ? ? ? ? ?datafile: 'Event13_Seizure_triggered_by_cortical_stim_Segment_1.edf'? ? ? ? ? ?headerfile: 'Event13_Seizure_triggered_by_cortical_stim_Segment_1.edf'? ? ? ? ? ?dataformat: 'edf'? ? ? ? ?headerformat: 'edf'? ? ? ? ? ? ? ? event: []? ? ? ? ? ?continuous: 'yes'

Hi both,There might be information on the date and time of recording in the orig field of the header, if that's what you're looking for. Don't know the name of the subfield from the top of my head.Arjen
