denprofile_analysis.tcl TCL script for VMD to calculate density profile normal to z-axis. Run the script with argument "usage" for more info, or see following example:
vmd -dispdev text -psf system.psf -dcd sample_run.dcd -args seltext "not water" outfile zinfo_timeseries.txt histfile denprofile.txt first 100000 last 200000 freq 100 |
Note that the -psf PSFfile topology description could be replaced with other filetype/filename options, e.g. -parm AMBERparmfile. Bin width and number are specified in the script, although they could be adjusted to be set at command line.
autocorr.awk AWK script to calculate autocorrelation of a time series.
histogram_dec.awk AWK script to create histogram.
histogram_discrete.awk AWK script to create histogram of discrete values (e.g. a variable taking integral values).
bootstrap_mean.awk AWK script to re-sample mean values in the bootstrap method.
