am i using knime correctly?

Hi,

 

II'm trying to run a simple workflow (sort), but use a file(65000) with Lines(Rows).

 

The workflow must read a text file and order all rows based a column and write a file with this results. (See the image attached)

 

The execution Log is:

 

!ENTRY org.eclipse.core.resources 2 10035 2013-07-25 12:11:44.189

!MESSAGE The workspace exited with unsaved changes in the previous session; refr

eshing workspace to recover changes.

INFO     main BatchExecutor      Workflow execution done Finished in 4 secs (476

6ms)

INFO     main BatchExecutor      ============= Workflow executed sucessfully ===

============

 

Also I exported the workflow for reuse with different files (which have the same format and the same file name), for this reason I run in command line mode (batch mode), using the following command line:

 

knime.exe -noexit -consoleLog -nosave -application org.knime.product.KNIME_BATCH_APPLICATION -nosplash -workflowFile="C:\temp\prueba1\job\Test1.zip"

 

Finally, this workflow works well with few lines files (100 or 1000 lines), but with a file of 65000 lines appear this log line "WARN     KNIME-Worker-0 File Reader      Node created an empty data table." and the result file is ever empty.
 
Is this the correct forma of use Knime?
 
Thank you.

Your goals seem well within the scope of KNIME useage.   The most likely cause of trouble is something specific to th elarger data file tha tyou are using.  Would it be possible to see a copy of such a data fiel uploaded here?
