Function Documentation

def IMP.EMageFit.solutions_io.gather_best_solution_results (   fns,
  fn_output,
  max_number = 50000,
  raisef = 0.1,
  orderby = 'em2d' 
)

Reads a set of database files and merge them into a single file.

Parameters
fnsList of files with databases
fn_outputThe database to create
max_numberMaximum number of records to keep, sorted according to orderby
raisefRatio of problematic database files tolerated before raising an error. This option is to tolerate some files of the databases being broken because the cluster fails, fill the disks, etc
orderbyCriterion used to sort the records NOTE: Makes sure to reorder all column names if necessary before merging The record for the native solution is only added once (from first file).
Note
This function is only available in Python.

Parameters
fnsList of database files
fn_outputName of the output database
raisefSee help for gather_best_solution_results()

def IMP.EMageFit.solutions_io.get_best_solution (   fn_database,
  Nth,
  fields = False,
  orderby = False,
  tbl = 'results' 
)

Recover the reference frame of the n-th best solution from a database.

The index Nth stars at 0

def IMP.EMageFit.solutions_io.get_fields_string (   fields)

Get a list of fields and return a string with them.

If there are no fields, return an *, indicating SQL that all the fields are requested

Parameters
fieldsA list of strings
Returns
a string
