TreMs formating not working cause @f0e5a361

Lines below won't work if the table has a single column. As TreMs are not mandatory, this introduce an error.

cols.num <- colnames(tab)[2:ncol(tab)]
tab[cols.num] <- sapply(tab[cols.num],as.numeric)

This is fixed in @63fffec1

The TreMs sheet for Soteska is also not working because the format is wrong
