Fnab

fnab builds nucleic acid entities from sequence. The sequence must be specified in one-letter code. Only one fragment can be created at a type (no spaces allowed unlike the 'fab' command).

Similar functionality is also provided by the graphical Builder in "Protein" mode.

New in PyMOL version 2.2

USAGE

fnab input [, name [, type [, form [, dbl_helix ]]]]

ARGUMENTS

• input = string: Nucleic Acid sequence in one-letter code

• name = string: name of object to create or modify {default: obj??}

• mode = string: "DNA" or "RNA" {default: "DNA"}

• form = string: "A" or "B" {default: "B"}

• dbl_helix = bool (0/1): flag for using double helix in DNA

EXAMPLE

The two examples produce the same result:

# Create default (B-DNA) chain
fnab ATGCGATAC

# Create B-DNA chain with specific name 
fnab ATGCGATAC, name=myDNA, mode=DNA, form=B, dbl_helix=1

# Create RNA chain
fnab AAUUUUCCG, mode=RNA
