Obtain A SSE Object From An SSE Sequence Vector

Inverse process of the funciton pdb2sse.

bounds.sse(x, pdb = NULL)

Arguments

x	a character vector indicating SSE for each amino acid residue.
pdb	an object of class `pdb` as obtained from function `read.pdb`. Can be ignored if `x` has 'names' attribute for residue labels.

Value

a 'sse' object.

Details

call for its effects.

Note

In both $helix and $sheet, an additional $id component is added to indicate the original numbering of the sse. This is particularly useful in e.g. trim.pdb() function.
