[gmx-users] Length of .xtc file in frames for C-Code

Hi :) I have a question to all the people who are familiar with C-code. How can I read in the total number of frames in my *.xtc file? Especially when I do the analysis somewhere in the middle? E.g: I have a file with 100.000 frames. When I start the programm with ./program -f traj.xtc then I

Hi GtrAngus, That's not possible, because the size of a frame is not fixed in XTC format. You can get an estimate by dividing the size of the file by the size of the first frame. That may not be accurate, though. Cheers, Tsjerk On Apr 3, 2014 6:31 PM, GtrAngus map...@online.de wrote: Hi :)

The xtc reading does this kind of guesswork seeking automatically, IIRC. Mark On Apr 3, 2014 10:12 PM, Tsjerk Wassenaar tsje...@gmail.com wrote: Hi GtrAngus, That's not possible, because the size of a frame is not fixed in XTC format. You can get an estimate by dividing the size of the file

Re: [gmx-users] Length of .xtc file in frames for C-Code

Hi to all! :) @ Mirco Wahab It is a mixture of both, I guess. I do know the total number of frames in my traj.xtc, it is 80.000. Furthermore, I am doing some averaging and other stuff, so I need the total number of frames. Actually, I could write a C-Code which is very very brute force, so I
