I have a file with data like:
The data to work with starts from the next line after '>header_xx'.
(1)
I want to search the three letter patterns 'CHH' or 'DDG' and replace C and G by exclamation ! so that CHH becomes !HH and DDG becomes DD!.
where: H = any letter but not G (example CHH = CAA, CAT, CTT etc) and D = any letter but not C (example DGG = ATG, AAG etc)
(2)Form a 3 letter window and slide 1 letter at a time; check for the patten described above until finish replacing.
Example output:
Thanks a lot for your help.

I'm doing a little work that involves computing the average completion time of the last 5 of many file decompressions. It's not too tough, but I'm wondering if maybe there's a better way to write it. This is a bash script; here's the current idea:

I have a sting of "0"s and "1"s that I need to analyze. I need to look at each "1" and determine if it is in a neighborhood that is enriched for "1"s which means it is one of at least three "1"s in a 4 character window. My desired output is a count of "1"s in an enriched area.

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.
