[FieldTrip] Reading data too slow

[张文嘉]

Dear all,


I have some problems in reading data into fieldtrip.
Specifically, I used EGI system to record EEG data and preprocessed them with Brainvison analyzer 
Then, I exported the preprocessed data into generic data format, making 3 files: .eeg, .vhdr and vmrk.
Last, I used ft_definetrial and ft_preprocessing to read these data into FieldTrip.
However, the reading is very very slow.


I tried to make only 2 channels left and tried methods as follow:
http://www.fieldtriptoolbox.org/faq/reading_is_slow_can_i_write_my_raw_data_to_a_more_efficient_file_format
But, they all did not work.


Does anyone know what I am doing wrong? Any advice very appreciated. 
Thank you
