WebIn that way, you can play with auto-picking parameters and see how selection changes on different values of parameters. For example, try to change the "picking threshold" from 0.8 to 0.6 or minimum inter-particle distance from 200 to 150, and you will get more particle selections.. To understand the value of FOM for the particular pick, you can run "Manual … Webrelion ’s implementation of the STAR format has the following rules (partially copied from BSOFT’s manual): The file name must end in a “.star” extension. Each file must have one or more data blocks. The start of a data block is defined by the keyword data_ followed by an optional string for identification (e.g., “data_images”).
