Support for .xyz/.m4d files (these files contain relevant header information) is implemented in fieldtrip just for backward compatibility. These need to be created from the raw data (using the pdf2set command (see the software manual of the MEG-system for reference)), but contain only limited header information (e.g. the balancing coefficients are not extracted). To me this sounds like double work, because FieldTrip can read the header information from the raw files directly.</div><div><br></div><div>Good luck,</div><div><br></div><div>Jan-Mathijs</div><div><br></div><div><br></div><div><br></div><div><br><div><div>On Mar 10, 2011, at 6:36 AM, Mehmet-Akif Coskun wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div style="font-family: arial, helvetica, sans-serif; font-size: 12px; background-color: white; "><p style="font-family: arial, helvetica, sans-serif; font-size: 12px; "><font face="'PrimaSans BT,Verdana,sans-serif'">Hello Dear Fieldtrip users,<br><br><br> I am a newbie in fieldtrip. I am having trouble reading the 4d data in fieldtrip. We are using a 248 sensor 4D MEG system. I have followed the discussion list and tried the suggestions but haven't succeeded reading the data. As far as i understand, i need some files (.xyz and .m4d) to be able to read the data but i don't also know how to obtain these files. Can anyone explain me the steps that i need to follow?<br><br><br>Thanks in advance,<br>Mehmet</font></p></div> _______________________________________________<br>fieldtrip mailing list<br><a href="mailto:fieldtrip@donders.ru.nl">fieldtrip@donders.ru.nl</a><br>http://mailman.science.ru.nl/mailman/listinfo/fieldtrip</blockquote></div><br><div apple-content-edited="true"> <span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; font-size: medium; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div>Dr. J.M.
