# # PURPOSE:
|
|
# # For a given vector of amino acid changes like A123T, V256F, E746_A750del
|
|
# # this function returns c(123, 256, 746) as amino acid positions of
|
|
# # the mutated residue.
|
|
# # In case of indels, it doesn't return the range!!
|
|
# # (i.e. returns only the start position)
|
|
|
|
|
|
# # USAGE:
|
|
# # AA.pos <- as.integer(MutSiteFind(mut))
