Dear Flavio, There are no updates available for PyRx 1.0 for Linux.
Dear Sarkis. I recently purchased academic license for PyRx 1.0 for Linux and managed to install it on a PC running Ubuntu 24.04. However, when running the program as root and checking for updates, I received the following message: Error in: <function checkforupdates="" at="" 0x1f736410=""> args: Python 2.6.6 (r266:84292, Jan 22 2014, 09:42:36) [GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux2 Type "help", "copyright", "credits" or "license" for more information.</function> Could you help me Flav...
Thank you very much! That helped. It gave me enough info to determine that I needed to install Gtk2. PyRx started right up after installing Gtk2.
Edit run.sh and replace: $PYRX_HOME/bin/python $PYRX_HOME/runPyRx.py &> /dev/null with $PYRX_HOME/bin/python $PYRX_HOME/runPyRx.py When you run from the command line it should tell what libraries are missing.
Apologies for the delay. The forum didn't send me an email like it used to do to let me know when there is a reply. I tried that today. When I ran that command, it said that there was nothing to install, likely because it was already installed from when I installed it previously. I re-ran the install commands for all three of those packages to make sure they were installed, and all of them were already installed. I even tried uninstalling PyRx and reinstalling it after running the three install commands...
I was able to start PyRx after yum install sdl12-compat.x86_64 Please let me know if it works.
Thank you for the message. I plan to install Fedora 43 over the weekend. I'll keep you posted on the progress.
I have a purchased version of PyRx 0.9.3 that was previously running with no issues on Fedora 42, which had been upgraded numerous times from earlier versions. Recently, I had to do a clean installation of Fedora 43. When I reinstalled PyRx, it would not start up. I followed the instructions on the download website to install libpng12.x86_64, SDL.x86_64, and mesa-libGLU.x86_64. (These instructions are still the same on the PyRx downloads website as when I first downloaded v0.9.3.) Mesa-libGLU was...
Please send me your order number.
Please, I have version 1.1, and I would also like to upgrade to 1.2
Please provide steps to reproduce this error. You can use https://sourceforge.net/p/pyrx/discussion/general/thread/1ba8825cf0/?limit=25#09f9 to fix it. However, I need to know how to reproduce this to fix it.
I am currently using version 1.1 and the update check says there are no new updates, but I noticed version 1.2 is released. I saw your reply to another user regarding this issue, stating that the new version requires a separate executable and that a coupon code is needed. Could you please provide me with the necessary link, coupon code, or instructions to upgrade to version 1.2? Thank you for your help. Best regards,
Software doesnt start
Dear Abdul. I need more information about your High-Performance Computing (HPC) cluster. Is this a Windows system with 120 CPU cores? You need a Linux version with PBS to run PyRx on HPC.
virtual screening on our institutional High-Performance Computing HPC cluster
Dear Dr We recently purchased PyRx software (Order PYR241121-4896-32101) and are attempting to deploy it for virtual screening on our institutional High-Performance Computing (HPC) cluster. We are encountering severe performance bottlenecks. Our internal IT team has identified the root cause as a significant underutilization of available CPU resources. While our HPC system provides a total of 120 CPU cores, PyRx is currently only utilizing a maximum of 3 cores during job execution. This means the...
Hi Sarkis I loved to get the coupon too, would you like to give the information to our institution, andi.suhendi(at)ums.ac.id is head of pharmacy program in our institution. Thank you. Best regards, B Santoso
Please undo it and use the same logic you used to set the workspace to C:\pyrx_dir\latihan01 and set it to the same with added _workspace. You can also change the workspace by editing the PyRx_workspace/preferences.ini in your home folder.

Hi Stephen, Yes, you need to restart PyRx for it to pick up the new workspace. It is better to use multiple workspaces rather than one big one for performance.
Hi Sarkis Just a follow up question. If I have two workspace folders called PyRx_workspace_project1 and PyRx_workspace_project2, can I switch between them by editing the PyRx preferences and choosing the appropriate folder for the AutoDock workspace, and still avoid the logging error? Thanks Stephen
Update Dockamon Path For New Dockamon Version.
Thanks, that worked. Cheers Stephen
Include SMINA box only if the smina path exists
Fix for https://sourceforge.net/p/pyrx/discussion/general/thread/d5fcde628e/?limit=25#9c26
Hi Stephen, It seems to happen because D:\Docking\PyRx doesn't include 'workspace'. You can fix it by replacing D:\Docking\PyRx with D:\Docking\PyRx_workspace, for instance. I'll look into fixing this in the next release. Thanks, Sargis
Hi Stephen, The new version requires an executable that can't be included with updates. I'll PM you a coupon code. Thanks, Sargis
Hi Sargis When I check for updates in PyRx 1.1 it tells me there are no new updates available, but I see in your blog that 1.2 has been released. Will that be made available via the update check process in version 1.1? Regards Stephen
Hi Sargis The following error message occurs in the PyRx logger window for every docking run I perform with Vina. It doesn't seem to affect docking, but it would be nice for it to be fixed so PyRx doesn't switch to the logger tab after each run.

Dear Sir, Thank you for the message. For 1, I would need the specs of your computer, the size of the protein and ligand, and the search space. My guess is that the search space is too large. I recommend making the search space smaller, otherwise,, it would take a long time for Vina to run. For 2) I need steps to reproduce it. In other words how did you get that error? 3) is a warning message that can be ignored.
Dear Sir, we purchased PyRx software for academic purposes, i am getting this error message attached in this email for your reference. insufficent memory Order ID: PYR241121-4896-32101 PyRx 1.1
The current version only supports python 2. I don't know what's causing this. I'm happy to help with any issues that happen with the paid version.
Runtime Std error This application has requested the Runtime to terminate it in an unusual way
Most probably the binding site you have chosen is wrong , if RMSD is this much . Are you talking about Redocking? Please mention the procedure you have followed
You can get the 64-bit version. I'll give a full refund, if it doesn't solve this issue .
Thank you very much for your prompt response. I request you kindly permit us to avail a trial version of the 64-bit version, so that we will get to know if it works to give our intended output. At this point of time, I have no option to pay the amount for the paid version as we have very limited funding for academic research. I am standing at a roadblock in my research because of this issue. Could you please help me with this on a humanitarian concern? It is great to have extended support like this...
Assuming that your computer has sufficient memory this can be solved buy getting the paid version. The free version is 32-bit while the paid version is 64-bit. I'm also happy to fix any issues you encounter with the paid version.
Dear Sir I am Bhrundha, a Ph.D. scholar from Kerala Agricultural University, Kerala, India. I am currently conducting research on small molecules and entering into the use of PYRX software (free version) for my work. It is great that we have an accessible free version of PyRx, for students like us who cannot afford even the Academic Version. Thank to your Team. I have done dummy docking assays to get used with the software, even with a batch of molecules of 25. However, I have been encountering an...
Hello sir. My latest version of PyRx is giving me high RMSD values above 100. I am a bit concerned if they are using AngStrom. Your response is greatly appreciated
Yes, in the latest version, there is an option to set Num modes for Vina https://sourceforge.net/p/pyrx/discussion/general/thread/cef07fd6ea/
Is there a way to increase number of docking poses in PyRx to 100?
Please get the latest version and let me know if this error remains. You could have started with thanking me for the free version, but no you want more. What are you expecting with the free version?
Please get the latest version and let me know if this error is still there,

@anchikam you just enter purchase order number in the checkout. If you do a purchase order through the site it would give you a link where you can make a payment.
@sarkiss I have the purchase order. What is the next step?
@anchikam you are welcome. You can do Wire Transfer, Check or Money Order or Purchase Order.
@sarkiss I have a purchase order ready. The grant I have doesn't have a credit card - it has to be done theough the budgeting. How can I proceed with the downloading in this case? Thanks again.
Thank you @sarkiss
Hi @anchikam , that link I provided list all the info needed plus has W-9. They can email b2b@fastspring.com for more info.
Hi @sarkiss, my university's purchasing has asked for additional information to be able to register the vendor. "Purchasing will need a copy of vendor’s W-9 and name and email or person completing registration. Please note, the person needs to be able to access company’s financial information." Would you be able to provide it (email)? Thank you.
Hi sure, you can get quotes for free from https://pyrx.sourceforge.io. Please let me know if you have any questions.
Hi, I am trying to get a quote for a commercial license: can you please point me in the right direction? Thanks

Dear Sarkis. I really appreciate your help. However, running PyRx in Windows is not an option for us, due to OS limitations. So, I try to install Ubuntu 24.10 64-bit, Kernel Linux 6.11.0-14-generic x86_64 replacing CentOS9. I successful install PyRx 0.9.2 in Ubuntu, but when I follow the instructions for update the version ( https://sourceforge.net/p/pyrx/code/HEAD/tree/PyRxDev/ ), I found the following error message: root@perseus:/usr/local/PyRx-0.9.2# ./run.sh root@perseus:/usr/local/PyRx-0.9.2#...
Add "is_pose" argument to AddMolecule and GenerateAssambly functions in molNavigator.py to explicitly make docking poses generated as BallsAndSticks in GenerateAssambly even if the number of atoms > 200. This previously caused issue with ligands > 200 atoms being rendered as Lines when selected from VinaWizard. The VinaWizard in OnSelect passes is_pose as True to the mentioned molNavigator.py functions to always display ligands as BallsAndDSticks even when ligands have > 200 atoms.
Dear Piyush, Thank you for your interest in purchasing PyRx. Unfortunately, lanthanum and similar elements are not supported by AutoDock/Vina and most forcefields, thus they cannot be processed. If you are interested, we can try to provide a custom approach, if you are only docking single elements (i.e. as in the ligand you provided), it might be possible to write a custom script to perform docking on the single elements, if you are interested in this service, please contact us via email (dallakyans@gmail.com...
