Hi I have a multi-step project I am working on and have been finding it difficult to come up with the correct approach.
The data I have been given resembles:
My goal here is to compare a large file such as this one to a set of references that are a single letter (T,A,C,G). I need to split the genotype in the given file into two individual letters and then compare this to the reference. If either matches the reference, then the program should move on to the next reference. If, however, neither letter is consistant, then the program should give an output of the index number and mutation type that corresponds to that data.
I am still fairly new to this so all help would be greatly appreciated.
Thanks!

Hi,
I'm new to perl and i have to write a perl script that will compare to log/txt files and display the differences. Unfortunately I'm not allowed to use any complied binaries or applications like diff or comm.
So far i've across a code like this:

ppmtosixel
ppmtosixel(1) General Commands Manual ppmtosixel(1)NAME
ppmtosixel - convert a portable pixmap into DEC sixel format
SYNOPSIS
ppmtosixel [-raw] [-margin] [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Produces sixel commands (SIX) as output. The output is formatted for color printing, e.g. for a DEC
LJ250 color inkjet printer.
If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled. A printer control header and a color assignment table
begin the SIX file. Image data is written in a compressed format by default. A printer control footer ends the image file.
OPTIONS -raw If specified, each pixel will be explicitly described in the image file. If -raw is not specified, output will default to com-
pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands. A raw file is often an order of magni-
tude larger than a compressed file and prints much slower.
-margin
If -margin is not specified, the image will be start at the left margin (of the window, paper, or whatever). If -margin is speci-
fied, a 1.5 inch left margin will offset the image.
PRINTING
Generally, sixel files must reach the printer unfiltered. Use the lpr -x option or cat filename > /dev/tty0?.
BUGS
Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion. If the original PPM maxval was
greater than 100, rescaling also reduces the image depth. While the actual RGB values from the ppm file are more or less retained, the
color palette of the LJ250 may not match the colors on your screen. This seems to be a printer limitation.
