Description

When running ctffind3 from different install (longboard/cronus3 - myamiweb/betamyamiweb) it seems that different conventions are used to define micrograph defocus: in some cases underfocus is defined as negative while it is positive in some others. As a result when looking at the ctffind estimation results in the image viewer, micrographs from a single data set have a mixture of postive and negative focus values but are all under focus.

  • Affected Version changed from Appion/Leginon 2.1.0 to Appion/Leginon 2.2.0

This bug also makes the ctf values pull out from prepRefineFrealign and makestack become a mixture of positive and negative because, once in the database, appion can not tell which version it comes from and getBestCtfValue function would take whatever has highest confidence.
