I was trying to create a BLAST database but I got this error

Building a new DB, current time: 12/03/2015 09:44:18
New DB name:   plant_protein
New DB title:  /home/sanjay/bin/Genomes/plant_protein_from_plantgdb.fa

file: plant_protein.pin
file: plant_protein.phr
file: plant_protein.psq

BLAST Database creation error: FASTA-Reader: No residues given

Then I looked whether my any FASTA sequence is empty or not by running this command

grep -c "^$" ~/bin/Genomes/plant_protein_from_plantgdb.fa

I found that there is one sequence which have only FASTA header. To remove the empty FASTA sequence I run this command

awk 'BEGIN {RS = ">" ; FS = "\n" ; ORS = ""} $2 {print ">"$0}' ~/bin/Genomes/plant_protein_from_plantgdb.fa >~/bin/Genomes/plant_protein_from_plantgdb.fasta

And finally I got the happy success message
