Distance Matrix Writer
Writes the content of a distance matrix column to an output
file. The output file will contain a row key column and a
triangular distance matrix, i.e. each row contains the
distances to the rows succeeding it.
Dialog Options
- Output File
-
Select the output file here. If the file name ends with
".gz", the file will be compressed.
- Distance Matrix Column
-
Select the column containing the distance values.
- Write Column/Row Header
-
Select this to include column and/or row header.
- Separator Char
-
The character used to separate entries in the table.
- Overwrite OK
-
Check this if an existing file may be overwritten (otherwise
the execution will fail to prevent unintentional overwrite)
- Writer Lower Triangular Matrix
-
Write the lower triangular matrix, that is, the first row will
contain zero or one entry (depending on whether the diagonal is
to be written) and each consecutive row one more entry than the
previous row. This option should only be enabled if the
distances are symmetric.
- Writer Upper Triangular Matrix
-
Similar to above, just write the upper triangular matrix.
- Writer Full Matrix
-
Write full matrix. This implies that also the diagonal is written
and each row will have the same number of entries.
- Writer diagonal values
-
Write also the diagonals when writing one of the
triangular matrices.
- Chunk Size
-
Does not have any influence on the outcome. It is used to reduce
the amount the table is iterated. Increasing the chunk size will
also increase the memory usage.
