[Mover] is not known to the MoverFactory


I'm running the 2016.20 weekly release of Rosetta and am running into some issues.

The bottom line is that this error comes up when I attempt to use certain Movers:

Error: ERROR: Exception caught by rosetta_scripts application:FastDesign is not known to the MoverFactory. Was it registered via a MoverRegistrator in one of the files (devel/ or protocols/

In this particular case it is FastDesign, but I'm not sure why it wouldn't be in the MoverFactory in the first place. I've also attached the full log file of the attempted run.

The documentation is out in front of the code.

Week 20 was the week before FastDesign was moved into the public code (from devel to protocols).  Unfortunately, shortly after that, many release builds in a row failed. That bug has been fixed but the release admin has not had a chance to put up the last couple of successful release builds.  

Hopefully he'll get a chance to do this week's or next week's weekly, which will have this code.  I expect to collect 3.7 release notes by the end of the month; that would have it too.

I am using the 2016.28 build and had the same problem with "BridgeChains" mover. This is how the mover is called in Brian's method paper: DOI:10.1007/978-1-4939-3569-7_20

I could't belive this mover is not added to the MoverFactory. Checking the available movers in the error log, turns out, the mover is actually called "BridgeChainsMover" in Rosetta.  The mover still has other bugs, I'll post another thread for this.

Best wishes,

That build looks (to me) like it should have the mover in place.  Can you attach the script you are trying to run, and the log file when it crashes?

MoverFactory prints a list of Movers it does have whenever it sees this error, immediately before the error.

Thanks Steve! You are right the mover is there but with a slightly different name than what's mentioned in the paper. I had edited my comment before seeing yours to epxlain this.

The mover has another bug though, I posted a thread here:

I would appreciate your thought on that.
