Folding Forum

Do you have a backup of the original trajectory data (created by the FahCore) or have the original files been deleted? We need to capture examples like that one.

It looks like that's a corner-case (in more ways than one ). I'll bet that the bond is correct, but the filter missed it. It probably shows exactly how the piece on the right should be joined to the piece on the left through a pair of external box faces.

If you relocate the piece on the right in the proper direction by the dimension of the box I'll bet it creates the proper length bond and stitches those two pieces back together although now the protein is no longer completely inside the box.

Actually it is still crunching:

What files you need exactly ?

Pause the WU. Make a backup copy, along with the .db that says it's there. Resume work and let it finish.

Are you and Jesse coordinating your development efforts?

PM send with link to G-Drive, 20MB tar file.

Thanks. The protein split glitch is a long-standing bug, and it'd be nice to track it down and fix it.

Have two more folding:

Project: 8574 (Run 1, Clone 6, Gen 473) and
Project: 8574 (Run 1, Clone 8, Gen 500)

Will pack them tonight when coming home.

Are you saying that these proteins also split into separate segments?
AND/OR
have bonds that stretch almost from one side of the box to the opposite side?

Here the one with gen 500



Different angle, same bond touch two borders



to cross check: also the official viewer has the phantom atom; circled here in orange; west coast of Latam

Great examples. That should help a lot in fixing the bug.

Here comes another interessting one: seems overlapping squares ? Or missing bond.

When I rotate the protein it seems the little chain is partially embedded by the bigger chain (part of chain)

Not "or" ... I expect it's "and"

If you look parallel to a side of the box, the shorter piece probably has one end very, very close to that face of the box and the longer piece probably attaches to the opposite face of the box. Find the atom on each chain that attach them to a face and manually add a bond between them.

If you know how to read the data created by the FahCore, I'll bet that bond is present in the original data created by the FahCore but hidden by FAHClient during the conversion to the API data. That's a bug that needs to be documented.

Installed the GROMACS 4.6.5 tools via Ubuntu-repository.

With those tools is rather simple to read the files from the working directory. The first learning: there can be more then one protein chain in the WU and sometimes something else (and not only water).
Like in P7505 there is a compound included called POPC (on the left); that one has quite a number of carbon atoms (comes at no surprise: 42 ) It looked wired the first times I saw it but it start to make sense.



One problem is that the trajectory provided by the API don't contain those additional information like number of protein chains, the identification of the side chains/residue or additional relevant molecules. GROMAS file has it all. Passthrough would be great as it would allow much simpler and diverse visualisation.

Anyway: I'm getting used to the files and continue my journey into the "boxes" ...

The learning continues ...

One question: are the coordinates in trajectory in Angstrom ?

I believe so.

Now here comes a totally messy one, lots of long bonds across the molecule, not only from side to side. Maybe still, as we dont know the size of the (repeating) box. don't open the video on mobile, bigger one

And in the second half the frame animation is swited on. Interesting that the protein just move along the y-axis.
