Yorodumi

Thousand views of thousand structures

  • Yorodumi is a browser for structure data from EMDB, PDB, SASBDB, etc.
  • All the functionalities will be ported from the levgacy version.
  • This page is also the successor to EM Navigator detail page, and also detail information page/front-end page for Omokage search.
