There might be differences in the chromosome names used in the genes file \

and the chromosme names used in the 'reference sequence' file. \
Please check that chromosome names in both files match.

NOTE: (Line breaks added for clarity)

I got this error when i was running the database build command by using gff. Please let me know how to solve this. Is it possible to change the gff file or i have to change the naming of my chromosome. I am making a reference of Vigna radiata.

How did that happen by the way? Are you not using a matching bundle of reference sequences and annotation for the analysis? You would have to change one of them as the error says.

do you have the reference genome in fasta file?

grep "^>" myRef.fa

will tell you the chromosome names, check that they match with the annotation
