ValueError: invalid literal for int() with base 10: 'auto'

Hello, I was trying to cluster two trajectories using the command: ttclust -f 1_SS_Unglycosylated-T1/step7_production-500ns.xtc 1_SS_Unglycosylated-T2/step7_production-500ns.xtc -t top.pdb -st "protein" -sr "backbone"

I got the following error: `**** ** TTCLUST 4.10.4 *****

---

NOTE : Per default the clustering is made on the BACKBONE of a PROTEIN PLEASE READ THE DOCUMENTATION AT https://www.github.com/tubiana/TTClust FOR PROPER USAGE

Several trajectories given. Will concatenate them. ======= EXTRACTION OF SELECTED ATOMS ======= NOTE : 'st' argument given.

P.S I am using the conda version of TTClust

Downgrade your ttclust version to 4.10.3. 4.10.4 is in beta testing. With version 4.10.3, worked for me. ttclust -f ../md_0_100_noPBC_noWAT_noJUMP_fit.xtc -t ../first_frame.pdb -l ttclust_clustering.log -st "all" -sa "name CA" -sr "name CA" -m average -aa Y --ngroup auto

HI, I have the same problem on Ubuntu 22.04. I have downgraded to 4.10.3 but I' receiving the following:

Can you suggest me something?

Thanks.

Try this command. mamba/conda install -c tubiana -c conda-forge ttclust==4.10.3

Hi, I have issued the command but after more than two hours it do not terminate.

Hi, sorry after 4 hour the command has terminated. Now I'll try again the analysis. Another question: the values in backbone.npy are nano meters or angstroms?

Thanks.

Switch from conda to mamba. Mamba is a fast, robust, and cross-platform package manager. https://mamba.readthedocs.io/en/latest/index.html

OK. Thanks. Saverio
