When I use edfread to read chb01_03.edf.seizures giving error!!!
Subscript indices must either be real positive integers or logicals.
Error in edfread1 (line 141)
hdr.label{ii} = regexprep(fread(fid,16,'*char')','\W','');
Error in Data_read_29_6_15_Seiz (line 3)
[a11,b11]=edfread1('chb01_03.edf.seizures');

I used this code that I got from comparing bytes in .edf.seizure files to the summary of the data in the folder:
function [ seizure_start_time_offset_in_seconds, seizure_length_in_seconds ] = get_seizure_period( annotation_file_location )
file_descriptor = fopen(annotation_file_location);
byte_array = fread(file_descriptor);
seizure_start_time_offset_in_seconds = bin2dec(strcat(dec2bin(byte_array(39)),dec2bin(byte_array(42))));
seizure_length_in_seconds = byte_array(50);
end

I have the similar problem. I can not read .seizure file from CBH_MIT database. What does this function
function [ seizure_start_time_offset_in_seconds, seizure_length_in_seconds ] = get_seizure_period( annotation_file_location )
do? How can i get seizure data and plot it?

My guess would be that chb01.edf.seizures is not an edf file, and is instead a file that contains a list of edf files.

You did not attach a file?
You might need to zip the file to attach the zip
