SPLICER DATA OUTPUT FILES

Splicer outputs up to seven different files

  1. Cull File - Binary ("hash") file containing data processing information
  2. Affine Table - Tab-delimited table of composite core depth offsets
  3. Affine Report - ASCII data file listing of time-stamped correlation/splices
  4. Splicer Table - Tab-delimited table of splices used to build spliced records
  5. Stratigraphy Table - tab-delimited table of stratigraphic ages and depth ranges
  6. Data File - ASCII file of Hole core data with MCD and MBSF depths
  7. Spliced Data File - ASCII core data file of a single spliced record

-------CULL FILE-------

This is a binary file which stores information about which samples were removed (culled) from the raw input data set based on the Cull criteria defined by the user. It is not editable.

------AFFINE TABLE-----

The AFFINE TABLE defines the depth offsets which must be applied to each core in each hole to align all stratigraphic features between holes. A binary toggle value (Y/N) indicates whether the core was actually shifted to match other cores.

Columns are: leg Site Hole Core Type Sect. MBSF Offset Toggle MCD

where,
MBSF = drilled depth of core top, meters below seafloor
MCD = depth-shifted composite depth of core top, meters composite depth

-----AFFINE REPORT------

The AFFINE REPORT is written automatically when the AFFINE TABLE is written. It contains all relevant information regarding the data which were used to establish the composite section and spliced records, as well as statistical information about the quality of each composite/splice action. All entries are time-stamped and the AFFINE REPORT is appended is the AFFINE TABLE is reread during another Splicer session.

-----SPLICER TABLE------

The SPLICER TABLE lists the tie points which are used to build the spliced data record from the depth-shifted core data. The file effectively summarizes the sampling pathway for obtaining a splice, composite section from any dataset. The SPLICER TABLE is in tab-delimited format, with each line indicating a stratigraphically-equivalent horizon. That is, Sample X in Hole A "ties to" Sample Y in Hole B.

In the example shown below, the splice begins at 926B, Core 1 (0 cm) and continues in 926B until section 1H-4 (19.5 cm). A splice is then made to Hole 926C 1H-2 (51.5 cm) and data is read in that hole unitl sample 926C-1H-6 (135.5 cm).

File format (Tab-delimited, all on one line): Site Hole Core Type Sect. Int1 Int2 mbsf mcd "tie to" Site Hole Core Type Sect. Int1 Int2 mbsf mcd

where, MBSF = drilled depth of core top, meters below seafloor MCD = depth-shifted composite depth of core top, meters composite depth

-----STRATIGRAPHY TABLE-----

If a STRATIGRAPHY FILE is read in initally, it is depth-shifted with the core data and the stratigraphic data are shown as range bars adjacent to the core data both in the Composite (left) and Splice (right) panels of the main Splicer window.

The depth-shifted stratigraphic data can be saved in a STRATIGRAPHY TABLE output file, which records the original stratigraphic depth ranges in the original (mbsf) and composite (mcd) depths.

STRATIGRAPHY TABLE File format (Tab-delimited, all on one line): Datum_name label TopAge BotAge Leg Site Hole Core Type Sect. Int1 mbsf Offset mcd Leg Site Hole Core Type Sect. Int1 mbsf Offset mcd

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.

-----DATA FILE-----

Once the compositing process is completed and all cores have been optimally
aligned relative to each other, the core data files with the calculated
meters composite depth (mcd) scale can be written to an output DATA FILE.

The OUPUT DATAFILE is written to the same location where the Affine Table
is located.

This file is essentially identical to the input file except that an
additional column containing the "meters composite depth" scale is
included.

If the raw input data have been processed by user-defined cull criteria (see
"Cull Data" help pages), then the output DATA FILE will only contain those data
which passed the defined cull criteria. If data were smoothed, then an additional
column containing the smoothed data will be written to the output DATAFILE.

DATA OUTPUT file format (Tab-delimited):

Site Hole Core Type Sect Int1 Int2 mbsf RawValue SmValue
Offset mcd

EXAMPLE:
926 B 1 H 1 13.50 13.50 0.14 10.00 10.00

Where:
RawValue: Data value from raw, input dataset
SmValue: Smoothed data value after processing during data input
Offset: Depth-shift in meters which must be added to (subtracted from) the
drilled depth (mbsf) to obtain the composite depth scale (mcd)
