what is lowercase letter mean? how can i convert all nucleotide to uppercase in fasta format?
meantime, identifier of sequences is like this.
>NW_011509460.1 unplaced genomic scaffold, scaffold730, whole genome shotgun sequence
>NW_011509461.1 unplaced genomic Scaffold670, whole genome shotgun sequence
that i want to convert them to:
