The following table describes the Match by options
on the Merge tab:
Option Description
Structure Search for exact match on
molecule or reaction in input file.
Other field Search for match on text or
numeric data.
Both structure
and other
Requires match in structure and
specified text or numeric data.
Custom SQL General mechanism for more
complex matching.
If no hits are found in the search, a new record is
added to the database. If hits are found, the first
record hit is modified as specified in the If match is
already on file options.
To choose how data is added to an existing database:
1. Click Overwrite, Append, or Merge.
2. If you chose Merge, click the Merge tab and
specify how to match the files and what to do
with matches that are already on file.
3. Click OK when you have entered all of the
options you want.
The file is imported into the database.
Changing the Data Field
Definitions
ChemFinder can determine what sort of fields to
create in the database, based on the characteristics of
incoming data. For example, if all items of type
“Melting Point” in an SDFile are numeric, then a
numeric field is created for them. The field scan
shows the results of this determination.
You can override this automatic determination. For
example, if you are loading another SDFile into the
same database later, and it contains Melting Point
entries with non-numeric text, then you may want to
establish this as a text field instead of numeric.
If you select a Text field type, you can specify the
width of the text field by entering a new value in the
Width box. Text fields are limited to 254 characters.
Longer strings of text must be stored in Memo
fields. Because the width of a text field cannot be
changed after it is created, make fields that are long
