# EDTSurf: Quick and accurate construction of macromolecular surfaces

# Authors

Dong Xu and Yang Zhang

## Introduction:

EDTSurf is a open source program to construct triangulated surfaces for macromolecules. It generates three major macromolecular surfaces: van der Waals surface, solvent-accessible surface and molecular surface (solvent-excluded surface). EDTSurf also identifies cavities which are inside of macromolecules. Recently, EDTSurf has been extended to calculate atom depth and residue depth to solvent-accessible surface.

## Usage:

EDTSurf -i inputfile ...

Specific options:

- -o prefix of output files (default is the prefix of inputfile)

- -t triangulation type, 1-MC 2-VCMC (default is 2)

- -s surface type, 1-VWS 2-SAS 3-MS 0-DEPTH (default is 3)

- -c color mode, 1-pure 2-atom 3-chain (default is 2)

- -p probe radius, float point in [0,2.0] (default is 1.4)

- -h inner or outer surface for output, 1-inner and outer 2-outer 3-inner (default is 1)

- -f scale factor, float point in (0,20.0] (default is 4.0)

Molecule is scaled by this factor to fit in a bounding box. Scale factor is the larger the better, but will increase the memory use. Our strategy is first enlarging the molecule to check if it exceeds the maximum bounding box. If yes, then reset a proper scale factor to fit the molecule in the maximum bounding box.

## Outputs:

1. outname.ply 	triangulated mesh surface (viewable by meshlab software)

2. outname-cav.pdb 	atoms surrounding each cavity

3. outname.asa 	accessible surface area with respect to each residue

4. outname_atom.dep 	depth with respect to each atom

5. outname_res.dep 	depth with respect to each residue
