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.
