4 years ago In matlab, use fopen to open the file, fseek to skip to the sample you want to start with, and fread to start reading data. Then fopen to open a second file for writing, fwrite to write the data that you read from the first file. Tip: with fseek you need to specify how many bytes to skip: each sample is 2 bytes and there are 385 channels per sample and 30000 samples per second. So you ought to skip 238530000N where N is number of seconds to skip. Tip2: in fread, use 'int16' as the format, which is equivalent to 'int16=>int16' which means "interpret the data in the file as int16, and return it to me in the workspace as int16".
You'll have to double-check that that works. Btw python has equivalent functions.
