THEREFORE, DATA WERE PROCESSED TO 2A AND SUBMITTED TO THE UCLA MBI DIFFRACTION ANISOTROPY SERVER FOR ELLIPSOIDAL TRUNCATION AND ANISOTROPIC SCALING. THIS PROCESS MAKES USE OF THE HIGHEST RESOLUTION DATA AVAILABLE, BUT RESULTS IN APPARENTLY LOW COMPLETENESS. USING CUTOFF CRITERIA OF F/SIGMA GREATER THAN EQUAL TO 3, THE SERVER APPLIED RESOLUTION CUTOFF LIMITS OF 1/3.0, 1/2.0, AND 1/2.2 A-1 ALONG THE THREE PRINCIPLE AXES A*, B*, AND C*, RESPECTIVELY. THE SERVER ALSO APPLIED AN ISOTROPIC B-FACTOR OF -22.75 A2. FOR COMPARISON, DATA PROCESSED TO 2.55A WITH NO ANISOTROPY CORRECTION WERE MORE COMPLETE BUT YIELDED POORER ELECTRON DENSITY MAPS (COMPLETENESS = 99.9% (100%),REDUNDANCY = 5.1 (4.9), RMERGE (LINEAR) = 0.118 (0.765))
In the structure databanks used in Yorodumi, some data are registered as the other names, "COVID-19 virus" and "2019-nCoV". Here are the details of the virus and the list of structure data.

EMDB accession codes are about to change! (news from PDBe EMDB page)
The allocation of 4 digits for EMDB accession codes will soon come to an end. Whilst these codes will remain in use, new EMDB accession codes will include an additional digit and will expand incrementally as the available range of codes is exhausted. The current 4-digit format prefixed with “EMD-” (i.e. EMD-XXXX) will advance to a 5-digit format (i.e. EMD-XXXXX), and so on. It is currently estimated that the 4-digit codes will be depleted around Spring 2019, at which point the 5-digit format will come into force.
The EM Navigator/Yorodumi systems omit the EMD- prefix.

Yorodumi is a browser for structure data from EMDB, PDB, SASBDB, etc.
This page is also the successor to EM Navigator detail page, and also detail information page/front-end page for Omokage search.
The word "yorodu" (or yorozu) is an old Japanese word meaning "ten thousand". "mi" (miru) is to see.
