In my previous e-mail I was not clear enough... extracting x and y values from xpm is easy and it is also easy to extract the density informations since they are represented by letters and for each of them a corresponding value of the number density is given at the beginning of the file. In my file I have 2000 values for the x and 2000 for the y and I got correctly 4000000 values for the density . However I don't understand how they are organized in the file. The first 2000 lines should be associated to the first value of the x and varying values of the y (2000 values) or is it the opposite or something else? Thank you
Alb ----Messaggio originale---- Da: [email protected] Data: 3-dic-2009 12.44 PM A: <[email protected]> Ogg: [gmx-users] g_densmap and xpm files Hi all. I have a question about xpm files produced by g_densmap. I would like, if possible, to extract information in numerical format, such as for example a single txt file with three columns 'x y density' for all the points on the grid chosen. These should be the information which are contained inside the xpm file but I cannot understand how to extract them. Any suggestion? Thank you for your help, Alb
