./../resources/alanine_dipeptide.pdb is not found #64

I encountered this error when I ran python3 ./main_work.py:

Where can I find the missing pdb file?

Hi, Thanks for your interest! You may find the file here: https://drive.google.com/file/d/1stCYe3ZGg3GnOrbVqCX_pu2uQ6Frxx6x/view?usp=sharing. Let me know if you have any questions.

Thanks for your reply! I downloaded the file but it is alanine_dipeptide.ipynb and not alanine_dipeptide.pdb. I opened alanine_dipeptide.ipynb and didn't find where to download alanine_dipeptide.pdb.

Sorry, it should be this one: https://drive.google.com/file/d/1SjFvrF7M4espMSS5bW1n-bwmY8pRkKZP/view?usp=sharing. Let me know if you have any issues.

@weiHelloWorld Now the script complains about missing 1l2y.pdb:

I have a look at the scripts and they require a lot of files in the MD_simulation_on_alanine_dipeptide/current_work/resources directory. However, it's empty in your repository. Could you please upload all the necessary files in MD_simulation_on_alanine_dipeptide/current_work/resources? Thanks!

I was trying to run the tests and hit this same error. I was able to find some of these files.

https://raw.githubusercontent.com/choderalab/openmm-tutorials/master/resources/alanine-dipeptide-implicit.pdb https://files.rcsb.org/download/1L2Y.pdb https://files.rcsb.org/download/2SRC.pdb Betahairpin.pdb is in here https://www.plumed.org/doc-v2.7/user-doc/html/tutorial-resources/lugano-5.tar.gz C24.pdb https://files.rcsb.org/download/6OV6.pdb

Sorry for the late reply! 1l2y.pdb and 2src.pdb are here:
