Hello everyone!
I try to use the ab-initio mode to do the docking.
Instead of specifying active and passive residues, I need to supply a HADDOCK restraints TBL file.
Could you please post a link to show how to generate a HADDOCK restraints TBL file?
Thanks!
Pei

For ab-initio docking no need to upload restraints!
Rather turn on ether the center-of-mass restraints or the random AIR ones

For anyone else that arrives to this post looking on how to generate restraints to use in HADDOCK, please have a look at [GenTBL](https://bianca.science.uu.nl/gentbl), an online tool to generate ambiguous restraints.

Indeed for ab initio docking you don’t need restraints, have a look at this link that has information on how to setup without and without information:
