All other sample files from previous versions of Neural Connection should be
moved to a different location or deleted.


Running the NET.AGT script
--------------------------
The NET.AGT tutorial script file should only be used with .CSV (comma separated
variable) or .SAV (SPSS) data files.


Running Neural Connection 2 with SPSS on Windows 3.x
----------------------------------------------------
Neural Connection 2 will fail to load a .sav file when run from SPSS if:

 1] The path name of the SPSS.INI file entry in the SPSS.AGT script file
    exceeds 128 characters.

 2] The path name of the .sav file being loaded into Neural Connection 2
    exceeds 128 characters.

Running Neural Connection 2 (NC2)
---------------------------------
 1] The arrow keys cannot be used to navigate the data window in the
    Input and Output tools. Use the PgUp and PgDn keys, or the scroll bar
    and mouse.

 2] When resizing the windows of the Input and Output tools with the mouse,
    the horizontal scroll bar does not always appear for all window sizes.

 3] On page 55 of the Neural Connection 2 manual it states that the upper
    limit for training is 15,000 records. This is a documentation error.
    The upper limit for training is 10,000.

 4] Variable names changed in the Input tool cannot be saved to their new
    name.

 5] The tools palette window cannot be closed using the CLOSE button (X).

 6] The data window of the Output tool does not scale to fit the number of
    records. The data window has a fixed size of 25,000 records maximum.
    The vertical scrolling bar navigates all 25,000 rows.

 7] The Data input tool File 'Save' and File 'Save As' supports the
    following file extensions:  .sav, .nna, .rdd, .txt. Any other file
    extension will result in an error message:
    "failed to create the file return code=-1.

 8] System Errors can occur in Neural Connection 2 when neural network
    tool parameters are set near or on their boundaries. System Errors have
    the following format:

    "An error has occurred in (tool). The operation cannot continue."

    This often results in one or more tools having to be deleted from the
    topology in order to continue using Neural Connection 2.

 9] The maximum number of records that can be passed into the Filter Tool
    is 10000, consisting of upto 5000 training and upto 5000 validation.
    For example, in a data file consisting of 9000 training and 3500
    validation only 8500 records will be passed into the Filter Tool
    (5000 training + 3500 validation).

10] Run data that does not have a target field cannot be processed. In
    order to process the Run data a 'dummy' target variable with empty
    cells has to be created.

11] 'Replace by mode' works only on numeric fields. 'Replace by mean'
    works only on symbolic fields.

12] NC2 only supports Microsoft Excel 5 .xls file format.
