Created attachment 705 modified version of ft_read_header when applying ft_read_header to EGI raw data (header format 'egi_mff_v1' 'egi_mff') function returns wrong number of samples (hdr.nSamples) propable reason: check for NS 4.5.4 picosecond timing is performed just for multi epoch data, should be done independent from number of data epochs suggested fix: add sanity and timming check in code lines 1001 - 1017 (see attached file, modified version of ft_read_header) hint: since I do not have multi epoch EGI data I was not able to test the modification
