Digest
function
(from OrgMassSpecR package)allows maxCharge to be set to calculate precursor m/z
digestMod(sequence, enzyme = "trypsin", missed = 0, maxCharge = 8,IAA = TRUE, N15 = FALSE, custom = list())
sequence |
a character string representing the amino acid sequence. |
enzyme |
is the enzyme to perform in silico digestion with |
missed |
the maximum number of missed cleavages. Must be an integer of 0 (default) or greater. An error will result if the specified number of missed cleavages is greater than the maximum possible number of missed cleavages. |
maxCharge |
numeric max charge charge for predicted precursor m/z |
IAA |
logical. TRUE specifies iodoacetylated cysteine and FALSE specifies unmodified cysteine. Used only in determining the elemental formula, not the three letter codes. |
N15 |
logical indicating if the nitrogen-15 isotope should be used in place of the default nitrogen-14 isotope. calculation |
custom |
list of custom masses |
