How to determine variables between two lines of input?












2















In my project, I have to iterate through files using Java. The idea of it is processing genome data and outputting it to a new file.



Here is an example from a couple lines of data we have to go through:



cure for cancer protein
ATGCCACTATGGTAG
captain picard hair growth protein
ATgCCAACATGgATGCCcGATAtGGATTgA
bogus protein
CCATt-AATgATCa-CAGTt


I am struggling on how one would logically decipher between the name for the region ("cure for cancer protein") and the following sequence of characters. I can get the file to display all info easily, but I need to process the sequence of characters differently than the region name and I can't figure out how to logically determine if the line is a region name or a sequence.



Any help would be greatly appreciated.

    Based on your example, the names appear on even line numbers, and the proteins appear on odd line numbers. The names start with a lowercase, not the sequences. The names contain spaces, not the sequences.

  • Ah, the spaces. I didn't think of that. Thank you!!

    Either you find a rigid way of distinguishing them (even f it requires reworking some files by hand, and imposing stricter formatting rules for future files), or you're forced to use heuristics. Frankly, using such a loosely defined file format for a system dealing with "cure for cancer proteins" is scary. Why not use a well-defined file format, like JSON, XML, or even simpler conventions like starting a name by #?

What about using RegExp? I think you can define is your line contains [ATGC-] only.
