RSR is case insensitive. If your input contains non-base symbols (A, T, G, C), these characters will be stripped before parsing. The RSR interpretation of your input can be seen on the result page.
RSR allows you to create your own sequences that are not included in the presets.
The RSR custom sequence code is as follows:
Name, Nucleotides
Name, Nucleotides
If name is omitted, your sequence will simply be referred to as "Custom Sequence X", where X is a number. Sequences are separated by newlines.
This example code will create three custom sequences.
My Sequence, ATTTTA
Another Sequence, GCTTCG
GCCGCC
The output will be:
