That was a problem I didn't notice, but it can be easily solved.
Remove "BEGIN { h=0 }", and add "h=0" to the "FNR == 1" action part.
i.e. "FNR == 1 { h=0; if(header!="") ....}"

Hi again,

I thought about modifying the script a little bit in order to add more option for the output.

For example I would like to get the 4 value before and after a local maximum within a file. For this I think I need to store the values of 9 sukzessive lines respectivly for comparison.

Code:
if ($2 in line X < $2 in line X-1) {print $0 of X-4, $0 of X-3, $0 of X-2, $0 of X-1, $0 ofX , $0 of X+1, $0 of X+2, $0 of X+3, $0 of X+4}

However I am not sure how and where to implement this in the current script. I tryd to creat an array but this doesen't seem to work...

What approach would you suggest?

Have a great weekend!
Daniel


ps: my current code
Code:
BEGIN     {
    print "trajectory= traj molecules= mol Peptide= pep resid(CA?)= res contact= so (max)solv/sphere= n Radius(A)= r" "first hill= gear";
    printf "%6s %6s %6s %6s %6s %6s %6s %6s\n ", "traj", "mol", "pep", "res", "co", "n", "r", "gear"; 
    } 

    

    NR == 1        {traj=$2;
            mol=$1;
            pep=$3;
            res=$5;
            so=$6;
            }
    FNR == 1    { 
            if(header!="") 
                {

                printf "%6.0f %6s %6s %6s %6s %6.1f %6.1f %6.1f\n", traj, mol, pep, res, so, h, max, gear; 
                traj=$2;
                mol=$1;
                pep=$3;
                res=$5;
                so=$6;
                h=0;
                max=0;
                help=0;
                #gear=0;
                } 
            header=$0; next; 
              } 

    
    {if (substr($2,3,5)/100000*10^(substr($2,9,3))>h)     { 
                            
                            h=substr($2,3,5)/100000*10^(substr($2,9,3))
                            max=(substr($1,3,5)/100000)*10^(substr($1,9,3))    
                            }
    else     {
        };

    


END     {
    printf "%6.0f %6s %6s %6s %6s %6.1f %6.1f %6.1f\n ", traj, mol, pep, res, so, h, max, gear;  
    }
