FR F - Read (sets) global symbolic (string) variables from a file

PURPOSE

Associates a character string with an string (symbolic) variable name. Reads both variable name and variable value from a text document file. 'FR F' differs from 'FR' and 'FR L' in that the string variables are 'global' and are accessible from all SPIDER procedures in the following SPIDER run.

SEE ALSO

FR	[Read (sets) a local string (symbolic) variable]
FR G	[Read (sets) a global string (symbolic) variable]
FR L	[Read (sets) a local string (symbolic) variable]

USAGE

.OPERATION: FR F

.ENTER TEXT FILE: txtfi
[Text file containing tuples of string (symbolic) variable names and their associated values.]

1. Example of Text document file contents.

[angles_file] angles001
[projections_file] proj{***[num]}
[magnification]25001

NOTES

1. This operation is useful when writing procedures which need the same input values or when creating parallel SPIDER runs.

2. Register variable substitutions occur when the value is used, not at time of input.
