arithmetic operations on 1 column of a file

Hi,

I have a file with thousands of lines like this:
Code:
Chr1    477515    .    ACCCC    ACCC    17.7    .    INDEL;DP=17;AF1=1;CI95=0.5,1;DP4=0,1,0,3;MQ=32;PV4=1,0.036,1,1
Chr1    481987    .    A    AAAT    62    .    INDEL;DP=11;AF1=1;CI95=0.5,1;DP4=0,0,1,3;MQ=41

I want to make a file with the sum of the first 2 numbers after DP4 in one column and the sum of the last two numbers of DP4 (before ;MQ...) in another column. How can I do that simply with some unix commands?

Expected output (for the two example lines above):
Code:
1 3
0 4

NAME
paps - UTF-8 to PostScript converter using Pango SYNOPSIS
paps [options] files... DESCRIPTION
paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves through the pango ft2 backend. OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. --landscape Landscape output. Default is portrait. --columns=cl Number of columns output. Default is 1. Please notice this option isn't related to the terminal length as in a "80 culums terminal". --font=desc Set the font description. Default is Monospace 12. --rtl Do right to left (RTL) layout. --paper ps Choose paper size. Known paper sizes are legal, letter and A4. Default is A4. Postscript points Each postscript point equals to 1/72 of an inch. 36 points are 1/2 of an inch. --bottom-margin=bm Set bottom margin. Default is 36 postscript points. --top-margin=tm Set top margin. Default is 36 postscript points. --left-margin=lm Set left margin. Default is 36 postscript points. --right-margin=rm Set right margin. Default is 36 postscript points. --gutter-width=gw Set gutter width. Default is 40 postscript points. --help Show summary of options. --header Draw page header for each page. --markup Interpret the text as pango markup. --lpi Set the lines per inch. This determines the line spacing. --cpi Set the characters per inch. This is an alternative method of specifying the font size. --stretch-chars Indicates that characters should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops behaviour. AUTHOR
