Hi,
I am not sure to understand what you want...
Nevertheless take a look at "GDF File Reader" and "GDF File Writer" boxes.

Dear mshh,

if you're ok to use GDF files, then what nbaron said is perfect.

If you want a convenient way to read your files from another application, have a look to the CSV file writer. It is basically a text file with coma separated fields

Hope this helps,
Best regards,
Yann

i mean i want to take signals from eeg module was recorded for pateint

Hi mshh,

If you are using openvibe to record your EEG data, then the format of the files depends on what file writer you were using.

If you recorded your data using a GDF file writer box, then the format is GDF, and you need to use the GDF file reader box to read the data for any offline processing.

If your EEG data come from another software (for example a proprietary software given by the EEG manufacturer), then we can't know what is the format of your data files ! But you can ask the manufacturer...

for recall (from FAQ) here is the current openvibe capabilities :

File reading and writing
- Generic files (r/w) (a.k.a. openvibe format)
- GDF files (r/w)
- BCI Competition IIIb (r)
- Brainamp files (r)
- CSV files (w)
