Looping options

The -loop option specifies the type of data detection loop. Allowed values are `list', `inf', `wait', `flag' or 'file'. In almost all cases of offline use, `inf' is most appropriate.

-loop list

Default when using the -list option. The pipeline will stop once the observations in the list have been reduced.

-loop wait

Waits for data to appear before timing out. Data is reduced and the pipeline waits for the next file.

-loop inf

Do not wait for data. Simply reduce data starting with observation specified by -from and continuing until no more files are present. Implicitly used when -from is specified. This is the fastest way of reducing data offline.

-loop flag

Waits for completion files to appear (flags) before processing the data. Data is reduced and the pipeline waits for more data by checking the presence of a flag.

-loop file

Works much like -loop list except that looping is carried out over a list of arbitarly named files input from the -files command line option.

-loop task

Obtain data from a remote (DRAMA) task.

See DataLoops for more information on looping schemes.
