Hi! I am getting the following error after I select the path of the XPT files, choosing one of the three configurations (WebSDM or Janus or Open CDISC) and then clicking the start button. I'll appreciate your help. Thank you. Paul

Hi Paul, Thank you for the feedback. Sorry to hear that you're having trouble. The problem that you're experiencing indicates an oddity with your SAS XPT files, or with the code that reads them. Do you know if there's anything that would be different between your files and those from the pilot study, for example? The code that parses XPT files has been significantly improved for the upcoming Beta release (especially the code relevant to your error), so if it is a specific problem with the code, hopefully it will be resolved in that version. If you'd rather just wait until then to see if there's still an issue, you can let us know if you still have trouble by posting reply here or creating a new topic in the Support forum. Regards, Tim

Check if you use the XPORT engine to produce your xpt files. http://www.sas.com/govedu/fda/faq.html

Hi,

 

I am running the most recent Beta release but am still getting a very similar error.  I have created my .xpt files using the XPORT engine, so I'm not sure what could be the problem.  The validator runs successfully on the CDISC Pilot .xpt files and on all .csv files, but I can't get it to work on any of the .xpt files that I have created.  Any guidance would be appreciated!

 

Thanks,

Heli

Hi,

 

Just to be clear, are you running a Beta release, or our latest release (which is a production release)? To check, you can launch the GUI and go to the Help menu, and click About OpenCDISC Validator, which should tell you the version.

 

If you are running a Beta release still, please update your version by downloading the latest version. If you are running the latest version, can you please copy the exception exactly how you see it? This will help us determine where exactly the error occurred.

 

Also, if possible, we would appreciate it if you were able to send us one dataset that had the same number and type of variables, but containing made-up data (the variable names are also irrelevant, those can be random too). This way we will hopefully be able to recreate and diagnose the problem here.

 

Regards,

   Tim
