How To Fix solvate.tcl: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu solvate.tcl is provided by packmol package.

packmol is:

Initial configurations for Molecular Dynamics Simulations by packing optimization.

Packmol creates an initial point for molecular dynamics simulations by packing molecules in defined regions of space. The packing guarantees that short range repulsive interactions do not disrupt the simulations.

The great variety of types of spatial constraints that can be attributed to the molecules, or atoms within the molecules, makes it easy to create ordered systems, such as lamellar, spherical or tubular lipid layers.

The user must provide only the coordinates of one molecule of each type, the number of molecules of each type and the spatial constraints that each type of molecule must satisfy.

The package is compatible with input files of PDB, TINKER, XYZ and MOLDY formats.

See http://m3g.iqm.unicamp.br/packmol for more information.

To fix this problem, we can install more using the command below.

sudo apt-get -y install packmol

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install packmol.

sudo apt -y install packmol

Or if you have aptitude installed you can use the following command.

sudo aptitude install packmol
