You can't expect characters that are used to split a string to be part of the result. If you split "1,2,3,4" on the comma, by definition the comma is not an allowed member of a field. Same goes with a bracket expression such as "[ACGT]"; splitting on such an expression forbids A, C, G, and T from occurring in a field.
Assuming I understood what were trying to do, the semicolons in your bracket expressions are incorrect. Characters in a bracket expression should not be delimited. To split on the four letters "A", "C", "G", and "T", "[ACGT]" is all that's needed. Adding those semicolons will cause splitting on semicolons as well.
Looking at your data:
If you just want to print the highlighted base sequence, and if its always preceded by the final number in the line, the following will do:
Or if the base sequence always begins at the 4th character past the final underscore:

I have gone through all the threads in the forum and tested out different things. I am trying to split a 3GB file into multiple files. Some files are even larger than this.
For example:

This is very slow and it splits the file with 3 million records in each... (10 Replies)

Dear colleagues! I want to create a script which will take each file from the list and then parse it filename with awk/split. I do it this way:
for file in `cat /$FileListFN`; do
echo `awk '
{N=split(FILENAME,FNParts,"_")}
{for (i=1; i<=N; i++)

Hello;
I have a file consists of 4 columns separated by tab. The problem is the third fields. Some of the them are very long but can be split by the vertical bar "|". Also some of them do not contain the string "UniProt", but I could ignore it at this moment, and sort the file afterwards. Here is... (5 Replies)

Can awk split be used to do this?
I have done this without using split, but the process is quite tedious.
Any help is appreciated! (4 Replies)
I am trying to run the awk below. My question is when I split the input, then run anotherawk to perform a calculation using that splitas the input there are no issues. When I try to combine them the output is not correct, is the split not working or did I do it wrong? Thank you :).

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.
