RNA structures (DSSR) / Re: strange residue number after dssr --view option

« on: August 06, 2018, 05:40:26 pm »

Hi Xiang-Jun,

Thank you very much for your explanation. I will fix the server to correctly represent these structures (such as 3mgp)  with conflicts between "_atom_site.label_seq_id" and "_atom_site.auth_seq_id".

RNA structures (DSSR) / strange residue number after dssr --view option

« on: August 06, 2018, 01:10:13 pm »

Hi Xiang-Jun,

I'm using the following command to convert a DNA\protein structure into its best view conformation. (3mgp.cif is downloaded from PDB database).

x3dna-dssr -i=3mgp.cif -o=3mgp_view.cif --view

The weird thing is the residue number index of the DNA part from original file (3mgp.cif)  is from 1 to 147. However, the corresponding residue number index from best view file (3mgp_view.cif) is from -73 to 73. I'm wondering is there an opinion to keep the residue renumber same between the original file and dssr output file? Thank you. 

For example, the beginning DNA part of 3mgp.cif is:

RNA structures (DSSR) / Web DSSR for dissecting the spatial structures of nucleic acids

« on: July 29, 2018, 02:16:30 pm »

Web DSSR is a user-friendly web-based interface for analyzing and visualizing three-dimensional (3D) nucleic-acid-containing structures. The server allows the user to determine a wide variety of conformational parameters in a given PDB ID or uploaded structure. Meanwhile, the secondary structure visualization component offers simultaneously highlighting of 1D, 2D, and 3D nucleic-acid structures.

The wDSSR web server is located at http://web.x3dna-dssr.org/.

Any questions and bug reports are welcome!

Thank you so much for your quick response. Just now I did a test and found a interesting thing.
I uploaded the 5afi.cif file (26MB) to the web server from a local machine, it works.
I fetched 5afi ID directly in the web server, it failed.

Dear Xiangjun,

I used DSSR-enhanced visualization web server to display ribosome structures such as 5afi, 5j4b. All my tried failed. I'm not sure it is my browser problem or the web server inner error. Thank you.

Dear Xiangjun,

I tried to use the following dbn file generated by DSSR and display its RNA secondary structure in forna (a RNA secondary structure visualization tool). However, it looks like forna doesn't recognize multiple sequences and "&" notation. It there a way to get around this? Thank you.
