<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; ">Hi Dorothea,<DIV><BR class="khtml-block-placeholder"></DIV><DIV>If you intend to use Fieldtrip for subsequent analysis of your data then if may be a good idea to use the (slightly) higher level reading functions, e.g. read(_fcdc)_data and read(_fccd)_header, since these will return the appropriate data structures. Even if you just want to read the data into an array and do your own stuff, then using the read_data function is a good idea, as it provides a very clean interface for the readers for individual formats.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV><DIV><BLOCKQUOTE type="cite"><SPAN class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><DIV class="Section1"><P class="MsoNormal"><FONT size="2" color="navy" face="Arial"><SPAN lang="EN-GB" style="font-size:10.0pt;font-family:Arial;color:navy; color: rgb(0, 0, 128); font-size: 13.3333px; "><SPAN class="Apple-style-span" style="color: rgb(0, 0, 128); font-family: Arial; font-size: 13.3333px; ">I am trying to read in EEProbe cnt files.
