The proportion of the genome of strains containing crispers is too small

[qianxin-kxy]

A very useful tool. I used this tool to process the genomes of over 900 strains of Acinetobacter, but only over 50 strains of the genome were found to contain crispers. I feel that the proportion is a bit small, but I don't know where the problem is or is it true?

Here is the code I used

$ for file in /data/users/infile/*.fasta; do minced $file > $file.txt; done
