Introduction

The [Vina] Basic Docking Colab Notebook is a widely used tool for molecular docking simulations. However, users have reported encountering an import error when trying to run the notebook, specifically with the 'prody' package. In this article, we will delve into the possible causes of this error and provide a step-by-step guide to resolve it.

Understanding the Error

The error message indicates that there is a problem importing the 'checkAnisous' function from the 'prody.utilities' module. This function is used to check the anisotropy of a protein structure. The error message suggests that the 'checkAnisous' function has been removed from the 'prody.utilities' module, which is causing the import error.

Possible Causes of the Error

There are several possible causes of this error:

  • Outdated Notebook: The notebook may be outdated, and the 'prody' package has been updated to remove the 'checkAnisous' function.
  • Incorrect Installation: The 'prody' package may not be installed correctly, or the installation may be incomplete.
  • Conflicting Packages: There may be conflicting packages installed in the environment, which is causing the import error.

Resolving the Error

To resolve the error, follow these steps:

Step 1: Update the Notebook

First, update the notebook to the latest version. This will ensure that you have the latest version of the 'prody' package, which may have resolved the issue.

Step 2: Install the Correct Version of the 'prody' Package

If updating the notebook does not resolve the issue, try installing the correct version of the 'prody' package. You can do this by running the following command in a new cell:

!pip install prody==1.94.1

This will install the 'prody' package version 1.94.1, which is the latest version that supports the 'checkAnisous' function.

Step 3: Check for Conflicting Packages

If installing the correct version of the 'prody' package does not resolve the issue, check for conflicting packages in the environment. You can do this by running the following command in a new cell:

!pip list

This will list all the packages installed in the environment. Check for any packages that may be conflicting with the 'prody' package.

Step 4: Uninstall Conflicting Packages

If you find any conflicting packages, uninstall them by running the following command in a new cell:

!pip uninstall package_name

Replace 'package_name' with the name of the conflicting package.

Step 5: Reinstall the 'prody' Package

After uninstalling any conflicting packages, reinstall the 'prody' package by running the following command in a new cell:

!pip install prody==1.94.1

This will reinstall the 'prody' package version 1.94.1, which should resolve the import error.
