Request a script on manupilating the data. Please HELP!
Dear friends,

I'm struggling to preparing a bunch of gaussian input files, say manually. It's really a time-consuming work without any techniques. I suppose that it could be done by a smart script automatically. But I lack some basic knowledge on scripting. Please help!

My original input looks like,
Code:
 C              
 H                  1    1.07000000
 H                  1    1.07000000    2  109.47120259
 H                  1    1.07000000    2  109.47120261    3  120.00001480    0
 H                  1    1.07000000    2  109.47123158    4  119.99999268    0

the modified output should be in the following format,
Code:
 C              
 H                  1    B1
 H                  1    B2    2  A1
 H                  1    B3    2  A2    3  D1    0
 H                  1    B4    2  A3    4  D2    0
B1 1.0700000
B2 1.0700000
B3 1.0700000
B4 1.0700000
A1 109.47120259
A2 109.47120259
A3 109.47120259
D1 120.00001480
D2 119.99999268

Clearly to say, the script would do:
1. we would get the total line number N by "wc -l"
1. replace the numbers in third column by B1~B(N-1), respectively, and add B1~B(N-1) to the end of the file followed by the replaced number.
2. replace the numbers in the 5th column by A1~A(N-2), respectively, and add A1-A(N-2) to the end of the file followed by the replaced number.
3. replace the numbers in the 7th column by D1~D(N-3), respectively, and add D1-D(N-3) to the end of the file followed by the replaced number.

I hope I have already made a clear statement about this script. Please do me a favor. All you help will be greatly appreciated. Thank you in advanced!

Code:
OUT=outfile

awk '{for (i=3;i<=NF;i=i+2) 
       { if (i==3) $i="B"++j
         if (i==5) $i="A"++k
         if (i==7) $i="D"++l
       }
     }1' infile > $OUT

awk 'NF>1 {print "B" ++i,$3}' infile >> $OUT
awk 'NF>3 {print "A" ++i,$5}' infile >> $OUT
awk 'NF>5 {print "D" ++i,$7}' infile >> $OUT


Code:
$ cat outfile

      NF>6{f=$7;$7="D"++d; D=D (D?RS:x) $7 FS f}
      $1=$1
