BIOVIA Materials Studio
Materials Studio on Supercomputer
Dear MS community, My lab purchased Materials Studio last year in March 2024, and it was successfully installed on our personal workstation. I wanted to know if we can utilize our institute's Supercomputer to run the software without actually installing on it. We just want to use the advanced computing power of the Supercomputer to run our simulations faster. Please let me know the procedure. Regards.
CASTEP Band Structure
Dear all, I would like to understand how CASTEP in Materials Studio converts the raw band structure data from the output file foo.bands into the format used for plotting the band structure, which can be exported as a CSV file. I am not looking for the script used in this conversion or the plotting itself; rather, I want to understand how to manually perform this conversion. Specifically, I am interested in the step-by-step calculations involved, so that I can verify the first few data points

Solvation Free Energy
Hi MS Community, This is regarding calculating Solvation Free Energy (SFE) using Forcite module. So, basically I wanted to calculate SFE of Paracetamol (PCM) in Acetone (and in various other solvents and wanted to corelate it with the experimental values at 303.15K). I made two attempts with Acetone as solvent. Attempt-1: PCM molecules- 1 Acetone- 100 SFE turned out to be -94.295 kcal/mol which is highly unlikely. Now if you apply the formula, Solubility= exp( -SFE / RT) (provided by @TM in one
Learning MS Script
Hello community, I hope my message finds you well. I am a user of Materials Studio (MS) software, which I use mainly for calculations of adsorption, interactions and dispersion forces. However, I have noticed that the values obtained are abnormally high compared with those reported in similar studies, even though they were carried out using comparable parameters. I would therefore like to test the use of scripts in MS to better understand and identify the source of the problem.

Visualizing Molecular Distribution in Sorption Module
I am currently working on determining the diffusion coefficient of a gas through a clay mineral's nanopore. As a preliminary step, I ran a Sorption module simulation to identify the locations of gas molecules within the pore space. However, the results appear to display a density distribution rather than the spatial distribution of individual gas molecules. I would greatly appreciate your guidance on how to obtain or visualize the molecules in the nanopore instead of just the density output.
How to extract exchange-correlation potential (not energy) in CASTEP?
Hello there, I’m currently working on DFT calculations using CASTEP, and I was wondering if there is any way to extract the exchange-correlation potential from a CASTEP run. I’m aware that the exchange-correlation energy is printed in the .castep output file, but my interest is in obtaining the exchange-correlation potential itself — either as a numerical grid or any form that could be visualized or post-processed. Is there a way to extract directly or indirectly? Any guidance or

Help Needed!! Sending computation jobs on Material Studios to a High Performance Computing server (computer cluster)
Hello, I have been struggling to connect my MS software job control to a computer cluster to run heavy calculations and save on computational time. So far my problem has been connecting to the license server that is running on my MS computer. I cannot figure out if this is a firewall issue on the computer or on the HPC.

Metal oxides undergo geometric optimization and deformation in the COMPASS position
Seeking help from everyone, I have encountered a problem.The metal oxide in my model will deform after geometric optimization, and I am using the COMPASS position. I found that the reason may be due to the difference in charge caused by the unequal number of metal atoms and oxygen atoms in the nanocell, because the charge cannot be zero. However, even after manually balancing the charge, the nanocell still deforms during geometric optimization. I would like to consult with you for a solution.

Molecule Displacement and Structural Adaptation in Simulation
Hello, I simulated a molecular system in a box and removed its central region to accommodate another molecule, slightly larger than its radius.

How to calculate solubility of polymer-solvent?
Dear All, Can someone explain how to calculate the solubility of a polymer in different solvents using Materials Studio? Thanks Hakkim
Confusion about Dipole autocorrelation function analysis failed
When I calculated the molecular dynamics of condensed matter by Forcite and needed to analyze its Dipole autocorrelation function, he showed: Dipole autocorrelation function analysis failed. The time associated with the selected frames does not increase evenly with frame index., I don't know what's wrong, it's 144 frames, In the Origin Step analysis interface, 1frames 1.0ps. The origin of the file: I used a Perl script to perform a series of molecular dynamics, the density for its convergence of

Computing distances via script on .xsd file
Greetings I am working on a script that would take into input a .xsd file, which is the result of a DPD simulation (the final frame). It should evaluate a centroid by selecting the solute bead which is the closest to the center of the lattice box, than it computes the distances from this centroid to all solvent beads present in the simulation. The centroid is defined just fine, but it fails here at computing the distances, without any particular error message. I just take their coordinates and

Creating sets of DPD result structure
Greetings, I am working on solute and solvent mesomolecules on which I use the Mesocite DPD module. The mesomolecules are coarse-grained structures, with the solute having 3 beads (A1,A2,A3) and the solvent too (B1,B2,B3). After the simulation (when I obtain the final mesostructure $structure), I want to assign the solute beads and solvent beads to specific sets in order to perform analysis on them (Mesocite RDF, gyration radius, and so on.). However I am struggling with the MaterialsScript
