Structure Builder

Loading Structures

From Online Databases

  • catgo_fetch_crystal — Load crystal by formula or structure_id from OPTIMADE providers (mp=Materials Project, mc3d, alexandria, twodmatpedia, omdb)
  • catgo_search_crystals — Search and list multiple matches. Use this first when browsing, then catgo_fetch_crystal with a specific structure_id.
  • catgo_fetch_molecule — Fetch molecules from PubChem by name, formula, or SMILES.

Provider heuristics:

  • General inorganic crystals: mp (largest database)
  • 2D materials: twodmatpedia
  • Organic molecules: use catgo_fetch_molecule, not OPTIMADE

From Current Viewer

Call catgo_structure_info to inspect the loaded structure. All structure-modifying tools auto-fetch the current viewer structure — no need to pass structure dicts.

Atom-Level Operations

ToolUse When
catgo_add_atom / catgo_add_atomsAdding atoms at Cartesian positions (Angstroms)
catgo_delete_atomsRemoving atoms by 0-based index
catgo_replace_atomChanging element at a site
catgo_move_atom / catgo_move_atomsRepositioning atoms

Lattice and Cell Operations

ToolUse When
catgo_supercellExpanding unit cell by [na, nb, nc] or 3x3 matrix
catgo_set_latticeAdding/changing periodic cell (wraps molecules in a box)
catgo_mergeCombining two structures at a given position

Defect Engineering

ToolUse When
catgo_build_defectPoint defects: vacancy, substitution, interstitial
catgo_dopingSubstitutional doping (replace host with dopant)
catgo_substitutionCombinatorial multi-site substitution
catgo_intercalationInsert species (Li, Na) into layered structures
catgo_build_strainApply strain/deformation (Voigt notation or 3x3 matrix)

Nanostructures

ToolUse When
catgo_nanotube_buildCarbon or BN nanotubes from chiral indices (n, m)
catgo_nanotube_infoCompute nanotube geometry before building

Common Recipes

Doped supercell

  1. catgo_fetch_crystal → 2. catgo_supercell → 3. catgo_doping → 4. catgo_structure_info

Defective structure for DFT

  1. Fetch bulk → 2. catgo_supercell (large enough to avoid defect-defect interaction) →
  2. catgo_build_defect → 4. catgo_structure_info

Intercalated battery material

  1. catgo_fetch_crystal (e.g. MoS2) → 2. catgo_intercalation (species="Li") → 3. Verify

atom-ops

免费

One-shot recipes for adding, deleting, moving, and replacing individual atoms in the active CatGo viewer structure. Use whenever the user asks to "add an atom", "delete atoms", "remove this atom", "move atom N", "replace H with Li", or any single-atom edit — including "add a hydrogen on top of atom 12" / "delete atoms 5–9" / "swap the oxygen at site 3 for fluorine". Skips the discovery loop (no need to list structure tools or check adsorption sites first); goes straight to the matching `catgo_structure` action. Triggers in Chinese on 加原子, 删原子, 减原子, 移动原子, 替换原子, 增加氢, 删除氧, 把 ... 换成 ....
