I've been wrestling with this one: Mathscript vi with some csvread() statements (copied in from an old Matlab program I'm converting). I run the vi and it generates a file not found error: Error -90001 occurred at Error in function csvread at line 1. LabVIEW: File not found. The file might have been moved or deleted, or the file path might be incorrectly formatted for the operating system. For example, use \ as path separators on Windows, : on Mac OS, and / on Linux. Verify that the path is correct using the command prompt or file explorer.=========================NI-488: Nonexistent GPIB interface.Of course before this I made sure to set the path using the Mathscript window options menu to the full path where the files are (and the files are there). Here's the rub: if I open up the Mathscript window and cut and paste the exact code from my vi into the command line - it works perfectly - no errors. I must be doing something wrong. Is there maybe a global LV project search path that needs to be set or something. BTW: it's weird that the error comes from NI-488 GPIB interface - I'm not connected to any hardware - it's a completely sw application right now. Thanks in advance for any suggestions, Tom

Ranjit,

I'm glad to see everything is working. Thanks for posting the code snippet for future users to refer to!
