Hello,
I have this kind of protein sequence: YLLLEPYFAVWY in a column.
I would like to have each amino acid (letter) in distinct columns using the Regex Split node.
| YLLLEPYFAVWY |
| Y | L | L | L | ... |
Unfortunately, I do not know the regex that does that.
With ([A-Z]{1})(.*$) I get:
| Y | LLLEPYFAVWY |
which is nearly what I need, nearly...
Does anyone know the right regex?
Thank you
Nico
Wow, not easy. As I understand, regex cannot create automatic capturing groups, which is what you want. You will need to do ([A-Z]) repeatedly, finishing off with a .*
If someone knows a way, please share. Hardly ideal. A better way is...
Use string replacer node, choose regex pattern and put in ([A-Z])
In the replacement text, put $1, This will now separate all letters by a comma. Now use a cell splitter node, and use , as the delimiter. And specify to replace all occurrences.
Job done.
That caused me a lot of head scratching.
Simon.
Hello Simon,
This is wonderful! Thank you very much!
However, for those who would read us, the pattern is ([A-Z]){1}, and the replacement text is well $1, .
It seems this head scratching exhausted you ;)
