I know that's super confusing (total noob-sorry!). To clarify, I have a text file that looks like this:
407-OL? 408-2-OL? 408-OL? 418-het? 420-1 and 2- OL? 429-2-left unscored? 430-2-left both unscored? 431-1 and 2- Ri?? 436-1-just homozygote? 444-2-het? ins. both 456-2-ins 246 despite slight OL 456-1-ins 245 (weaker) 457-2-Ri?
I want it to return the numbers on the left (before the dash), but only for lines that contain a question mark. In other words, I want this to be the output:
407 408 408 418 420 429 430 431 436 444 457
Any suggestions would be amazingly helpful! Thank you!
