I want to identify and replace the third occurrence of the "T" character in each data row
AGCTTAGGCGAGUGCGAGTGCGATA replaces it at character 12 (base 0)
AGCTAGGCCGTAAAGCGAGGAGCCC only 2 occurrences, replaces nothing
CTAGCATGCAUGGGACCTAGGACCA replaces it at character 10
TAGAGATCGACGAUTTACGAGGTTC replaces it at character 13
This is a simple case. I'm looking for something like this that will work for any occurrence and any character or string more generally. I expect it will require REGEX, but I'm not yet proficient with it.
@pcatterson, as an FYI...if you get a workflow sent that is "beyond" your version, you can usually just open the YXMD in a text tool (like Notepad) and change the version to your earlier one. It's in the second line of code.
Of course the caveat is if the workflow uses tools that are in the newer version only, it won't work.
