Detailed Description

Class used for storing time gate durations.

Times are supposed to be relative to the scan start time.

Currently this class can read gate info from an ECAT6, ECAT7 and a 'gate definition' file. See the documentation for the constructor.

Will probably be superseded by Study classes.

void stir::TimeGateDefinitions::read_gdef_file

(

const std::string &

gdef_filename

)

Read the gate definitions from a file.

The filename can point to a simple ASCII text file. The format is a number of lines, each existing of 2 numbers

gate_num   duration_in_secs

This duration is a double number.

This class in fact allows an extension of the above. Setting gate_num_of_this_duration to 0 allows skipping a time period of the corresponding duration_in_secs.
