Sequence Creation and Manipulation

Programs

  • GCG Programs
    • Assemble: Concatenates sequence fragments into a single sequence
    • Reverse: Reverses and/or complements a sequence
    • Seg: Replaces low complexity regions in protein sequences with X characters
    • Xnu: Replaces statistically significant tandem repeats in protein sequences with X characters
    • Simplify: Converts all symbols of the same type to the same symbol (e.g., to treat all hydrophobic amino acids as equivalent)
    • Shuffle: Randomizes the order of the symbols in a sequence without changing its composition
    • HmmerEmit: Generates new sequences that match a profile hidden Markov model
    • Corrupt: Randomly introduces small numbers of substitutions, insertions, and deletions into a sequence
    • Sample: Randomly extracts sequence fragments from sequence(s) to created new sequences
  • EMBOSS Programs
    • newseq: Creates a short new sequence from keyboard entry
    • revseq: Reverses and complements a sequence
    • trimseq: Trims ambiguous bits off the ends of sequences
    • cutseq: Removes a specified section from a sequence
    • extractseq: Extracts regions from a sequence
    • pasteseq: Inserts one sequence into another
    • splitter: Splits a sequence into (overlapping) smaller sequences
    • maskseq: Masks off regions of a sequence
    • maskfeat: Masks off features of a sequence
    • coderet: Extracts CDS, mRNA and translations from feature tables
