StringPadRight ["string",n]
makes string be of length n, padding it on the right with spaces or truncating it if necessary.
StringPadRight ["string",n,"padding"]
pads by repeating copies of the string padding.
StringPadRight [{"s1","s2",…}]
pads strings with spaces on the right to make them all the same length.
StringPadRight [{"s1","s2",…},n,…]
pads or truncates to make all strings of length n.

Details
- StringPadRight effectively places repeated copies of padding to the right of string, truncating them when a total width of n characters has been achieved.
- StringPadRight [BioSequence ["type","seq"],n,…] will apply the operation to the string "seq", yielding a BioSequence result.
- The following letter is used as the default padding for each type of biomolecular sequence if not otherwise specified:
-
"DNA"or "CircularDNA" N"RNA" N"Peptide" X
