Hello, I'm looking for a tool that might introduce mutations to genomes. The main idea is to test how mutations will affect mapping (both genome to genome, and short reads to genome). Any recommendations please? Have a great weekend!

You mean to mutate a fasta (genome sequence) or a fastq (reads) file?

BamSurgeon for spiking mutations into the reads.

snp-mutator for fasta files.

Try simutator, e.g., every 2kb where a region of length 1.5kb gets 30 snps, 2 insertion and 4 deletions up to length 10bp.

mutate.sh from BBMap suite. Take a look at in-line help for additional options.
