Colide writes the locations of significant storms to an SPDB database.

=== '''Overview''' ===

Colide takes storm information from a Titan database, determines which storms are significant in terms of longevity and area criteria, and writes the latitude and longitude of the storm initiation to an SPDB database.

=== '''Prerequesites''' ===

The following items are required:

* Storms data from Titan

=== '''Parameter file''' ===

Colide uses one parameter file that includes input/output directories and filters.

==== '''Ensure file is up to date''' ====

To obtain the default parameter file, use the following command:

<code lang="bash">/path/to/lrose/install/bin/Colide -print_params > param_file_name</code>

If you already have a parameter file and simply want to check for (and add) updated parameters while retaining current parameters, use the following command:

<code lang="bash">/path/to/lrose/install/bin/Colide -params orig_param_file_name -print_params > new_param_file_name</code>

==== '''Important parameters''' ====

Parameters

* fixed_const: fixed constant strings interpreted by user functions
* volume_before_filter: volume filters applied before the sweep filters; all filters available can be viewed with the -print_operators flag
* filter: filters to apply to sweeps; all filters available can be viewed with the -print_operators flag
* volume_after_filter: volume filters applied after the sweep filters

VirtVol Parameters

* trigger_url: oath to trigger off of
* input_url: names of parameter files for input paths
* output_url: names of parameter files for output paths

=== '''Running Colide''' ===

To check all command line options for Colide, including debugging options and file paths, type the following command into a terminal.

<code lang="bash">/path/to/lrose/install/bin/Colide -h</code>

To see all the filtering options for Colide, type the following command into a terminal.

<code lang="bash">/path/to/lrose/install/bin/Colide -print_operators</code>

Once your parameter file is complete, use a command similar to the following to run the application:

<code lang="bash">/path/to/lrose/install/bin/Colide -params param_file_name</code>

The user can also specify the location of cfradial files in the following manner:

<code lang="bash">/path/to/lrose/install/bin/Colide -f /path/to/cfradial/files/ -params param_file_name</code>
