Hi,<br><br>I am trying to run qdec for group analysis of subcortical and cortical volumes.  I have all of my data in an excel sheet (subject ID, age, gender, volumes of various structures) and am trying to convert this into a file that will be able to be opened in qdec.  I use a Mac, and I have exported the sheet into text-edit and then resaved it as &quot;qdec.table.dat&quot;.  This .dat file opens perfectly in text-edit.  However, when I go to load the table into qdec it gives me an error:  &quot;error loading the data table&quot;<br>
<br>Is the dat file I created not compatible with qdec?  If so, is there another way in which I can transfer my data into a dat file?<br><br>Thank you very much in advance for your help,<br><br>Matt<br>
