I am trying to set up an assembly in Jbrowse2. For that, I need an indexed Fasta file. I am using the following command line to convert my Fasta file to an indexed Fasta file.
samtools faidx /home/maliha/Downloads/jbrowse2/sequence.fasta
However, I got an indexed Fasta file containing just one line. I have attached the picture of that line to this post. Please do help me to figure out the problem.
