Open Stratigraphy file:

Splicer allows users to read, display, and depth-shift up to five different types of biostratigraphic (foraminifera, nannofossils, diatoms, radiolaria) and paleomagnetic (reversal) age control data. The files are in a standard tab-delimited format which can be exported from spreadsheet programs such as Excel (see "Stratigraphy Data --> Input" Help pages).

The user specifies the files to be read using "OPEN... --> STRATIGRAPHY FILE" under the FILE menu. Once located, the user identifies which type of stratigraphic data the file represents - this color-codes each of the five stratigraphic data types. When read, the data are plotted as range bars to the left of the core data. The user may click on the symbol of the stratigraphic label next to the range bar and the information about that datum will appear in the dialog box at the bottom of the main window.

--------STRATIGRAPHY DATA FORMAT----------
The files can be developed on simple spreadsheet programs (such as Excel or 
Kaleidograph) and then exported as tab-delimited files and then transfer to 
the Sun workarea.

Where: Datum_name: Up to 30 character-long string of the datum identifier. NOTE: There must be no spaces in this field, please use an underbar "_" or a Hyphen "-" instead of spaces, otherwise the file will not load properly.

Label: The user-defined abbreviation for the Datum_name which is suitably short for text display adjacent to the core data in the Composite and Splice panels of the main Splicer window. TopAge: Upper age limit (in Kyr or Myr) for the datum. If upper=lower, enter the same value in both fields. BotAge: Lower age limit (in Kyr or Myr) for the datum. If upper=lower, enter the same value in both fields. ________
