Hi:
I am using the g_sas with the -or option . The output file have 3 colums: first the res number, second the sasa value, third I dont know. To what corresponds the third columnin the file?
A quick peak in the source code:

        fluc2 = res_area2[res]-sqr(res_area[res]);
        if (fluc2 < 0)
          fluc2 = 0;
        fprintf(fp,"%10d  %10g %10g\n",res+1,res_area[res],sqrt(fluc2));

In other words, it is the standard deviation of the area over the trajectory.


Best regards
Anthony
