Count observed frequencies of words in a FASTA file, providing parameter values with interactive prompt:
compseq {{path/to/file.fasta}}
Count observed frequencies of amino acid pairs from a FASTA file, save output to a text file:
compseq {{path/to/input_protein.fasta}} -word 2 {{path/to/output_file.comp}}
Count observed frequencies of hexanucleotides from a FASTA file, save output to a text file and ignore zero counts:
compseq {{path/to/input_dna.fasta}} -word 6 {{path/to/output_file.comp}} -nozero
Count observed frequencies of codons in a particular reading frame; ignoring any overlapping counts (i.e. move window across by word-length 3):
compseq -sequence {{path/to/input_rna.fasta}} -word 3 {{path/to/output_file.comp}} -nozero -frame {{1}}
Count observed frequencies of codons frame-shifted by 3 positions; ignoring any overlapping counts (should report all codons except the first one):
compseq -sequence {{path/to/input_rna.fasta}} -word 3 {{path/to/output_file.comp}} -nozero -frame 3
Count amino acid triplets in a FASTA file and compare to a previous run of `compseq` to calculate expected and normalised frequency values:

Approximate the above command without a previously prepared file, by calculating expected frequencies using the single base/residue frequencies in the supplied input sequence(s):
compseq -sequence {{path/to/human_proteome.fasta}} -word 3 {{path/to/output_file.comp}} -nozero -calcfreq
