Title: Identify sugar type in the DSSR output
Post by: brinda.vallat on April 23, 2020, 01:38:19 pm
It would be useful if DSSR output can provide information regarding the sugar type for each nucleotide i.e., whether the sugar is ribose or deoxyribose.

For example, in the JSON output, there can be a new item within the "nts" object that provides this information:

"nts":[{"index":1,"index_chain":1,"chain_name":"N","nt_resnum":24,"nt_name":"A","nt_code":"A","nt_id":"1..N.A.24.", "nt_sugar_type":"ribose"............}]

I've just updated DSSR to v1.9.10-2020apr23. It has a new field named "nt_type", with possible values of "DNA", "RNA" or "unknown". Since the item is included in the nts[] array, I've used the name "nt_type" instead of your suggested "nt_sugar_type" (with values of "ribose" or "deoxyribose" etc).

Please download the updated DSSR (forget about the label, which still reads "v1.9.9-2020feb06"), and report back how it goes.

Best regards,

Xiang-Jun

I downloaded and tested the updated DSSR version. It works very well. Thank you!
