Dear FieldTrippers, I try to read EGI .ses file using hdr = ft_read_header('myfile.ses'), or hdr = ft_read_header('ttt.ses, 'headerformat', 'egi_ses') but get an error message: 'unsupported header format (unknown)' It is stated that FT reads EGI .ses files. Have anybody tried or have some tips? Elena
