" or ID's from any of the supported genotyping platforms.</LI>"
"<LI><B>column labels:</B> Controls whether the first row of the upload file is "
" interpreted as labels rather than data. If the first row contains text in the "
" numerical fields, or if the mapping fields are empty, it is interpreted by "
" \"best guess\" as labels. This is generally correct, but you can override this "
" interpretation by explicitly setting the control. </LI>"
