Please note that
If you want to detect potential CRISPR-Cas-related information on a gene sequence, select the Genome sequence button and upload the genomic sequence of a bacterium or archaeon. If you want to identify a potential Cas protein, select the Protein sequence button and upload either the bacterial or archaeal protein sequences.
The input file size is limited. If you wish to perform genome-wide or large-scale predictions, we recommend that you download the CRISPRCasStack offline toolkit(CRISPRCasStack) to perform your analysis locally.
We provide an example file containing 3 Cas proteins: Cas proteins
