Elena,<div><br></div><div>The FieldTrip wiki says that there is support for .egis, .sbin, .ses, .ave, and .gave <<a href="http://fieldtrip.fcdonders.nl/getting_started/egi">http://fieldtrip.fcdonders.nl/getting_started/egi</a>>, but it doesn't seem that the last three are actually supported. If you look in the fieldtrip-DATE/fileio/ft_read_header.m function, the only EGI formats supported seem to be the first two I mentioned (egis and simple binary), plus the new metafile format. You'll need to export your .ses file to one of these supported formats. I've had luck with egis and sbin (tip: I've found that egis is faster to read). I'll update the wiki.</div>

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