Unable to calculate estimated library size: samtools markdup
This is my command: snippy --outdir snps_output_rep4 --ref GCA_018093105.1_ASM1809310v1_genomic.fna --ctgs S.aureus_bat3_r3..contigs.fasta
I am getting error while running samtools markdup I am using contigs and ref genome in fasta format. PLease help me.
