I've got a file containing CDS mutation information of cancer genes.
The data have mutation positions and sequences in normal/cancer.
c.863_864insTCTG c.1799T>A c.1849G>T c.2504A>T c.2509_2510AT>CC c.2506_2508ATC>TTT
I want to extract positions from it, but no separator is there between numbers and text.
How can I separate them?
