Error messages 01

Error in data.frame: duplicate 'row.names' are not allowed
row.names有重复

Reason: We found that the main reason for this error is that when you prepare the traitdata file, there are many blank lines in the file, these blank lines will not be removed when import in to R. The first column will be converted to rownames. The blank cells was treated as repeat row.names.

Solution: Open traitdata file with software such as sublime text or editplus, delete all blank lines or other characters after useful information.
