Julia parser for the Stockholm file format (.sto) used for multiple sequence alignments of protein, RNA, or DNA sequences (Pfam, Rfam, etc databases). This package uses Automa.jl under the hood to generate a finite state machine parser.
Enter the package mode from the Julia REPL by pressing ], then
install with:
add BioStockholm
using BioStockholm
msa = MSA{Char}(;
seq = Dict("human" => "ACACGCGAAA.GCGCAA.CAAACGUGCACGG",
"chimp" => "GAAUGUGAAAAACACCA.CUCUUGAGGACCU",
"bigfoot" => "UUGAG.UUCG..CUCGUUUUCUCGAGUACAC"),
GC = Dict("SS_cons" => "...<<<.....>>>....<<....>>.....")
)
# read from file
# example2.sto contains an example Stockholm file
msa_path = joinpath(dirname(pathof(BioStockholm)), "..",
"test", "example2.sto")
msa_str = read(msa_path, String)
print(msa_str)
# read from a file or parse from a String
msa = read(msa_path, MSA)
msa = parse(MSA, msa_str)
# write to a file
write("foobar.sto", msa)
# pretty-print
print(msa)
print(stdout, msa)- when writing, long sequences or text is never split over multiple lines
- integrate with BioJulia string types
MIToS.jl is a package for analysing protein sequences that also supports parsing the Stockholm format (and many more things).
