A source contains the location of the local archive directory, picks directory, and station xml file. These folder and file locations can all be updated through use of actions - as they are all hot variables. To change the source open the change source dialog (default key-bind is P). Source files need not be contained in Lazylyst's main path.

To add a source to the saved sources, fill in the directory and file name paths and hit the Save Source button. To remove a saved source, click on the source in the Saved Sources list and hit delete. To edit a source, double click on the source, update the directory/file paths and/or source dictionary and hit the Save Source button.

To select a source to use, double click on a Saved Source (or optionally fill in the dialog without saving source) and hit the OK button. Note that if any of the entry lines are blank, or if the directory/file does not exist, updating will be cancelled.

Archive directory Contains all miniseed files in the archive, archive must have one of the extensions: mseed, miniseed, or seed. It is suggested to have archives which contain all station data for a given time period in the same file, as data can be loaded faster this way. The initial archive loading may take while depending on the archive size and directory structure, future loading makes use of a cached file. If any archive file has been edited, added, or removed - these specific files will be checked again.

Picks directory Contains all picks files of the current source. Picks files are in csv format where the columns are: StationCode, PhaseType, Timestamp(s).

Station xml file A station xml file providing all wanted station metadata to be used, xml contents are held in the hot variable staXml. The projection of the station locations is chosen through use of the preference staProjStyle. The projected X and Y values are plotted on the map widget (and are held by the hot variable staLoc).

Source Dictionary Holds set of dictionaries with custom values relating to the current source.

All of the files required the create a sample source are located in the ExampleSource folder in Lazylyst's main directory.
