Hi all, I’m running the CPORT analyses to prepare for the HADDOCK runs. For one of my structures I get an error and no active/passive residues (hopefully because of the error :)). The details are below [https://alcazar.science.uu.nl/serviceresults/CPORT/48432899/index.html](https://alcazar.science.uu.nl/serviceresults/CPORT/48432899/index.html) It looks like the BLAST search crashes? Could this be due to a mistake in the PDB file? It was generated in two parts by trRosetta and ‘fused’ in pymol, but the sequence is correct. Looking forward to the answer 🙂 Cheers, Richard ---

Considering that pretty much all servers fail, there must be a problem with your PDB file most likely. Without it, difficult to say what the issue is. ---

Okay, will investigate if i can find anything! Thanks for the prompt response 🙂
