<div dir="ltr"><div>Hi Geeta,</div><div><br></div><div>I don't know if anyone has replied to you yet. This appears to be a typical programming challenge, in which arrays that are different shapes can't be assigned in NCL. One of your files probably has a different dimension from the others. </div><div><br></div><div>Tools like ChatGPT "know" NCL and can be very helpful in explaining what is going on with your code and offering potential solutions. Here's a link to a chat where I simply put the text of your email into it and asked if it could figure out what was going on. It provided a good explanation and solution. </div><div><a href="https://chatgpt.com/share/69968a1a-b73c-800f-a291-aab0c2136ec0">https://chatgpt.com/share/69968a1a-b73c-800f-a291-aab0c2136ec0</a></div><div><br></div><div>I don't recommend using free-tier AI tools to blindly write or patch code for complex tasks, as I've observed them to lose context and lead one around in circles. However, for debugging errors like this, they are often very helpful. As with anything AI, one always needs to carefully check to ensure that the code solution works.</div><div><br></div><div>Best regards,</div><div>Jonathan</div><div><br></div><div><br></div><div><br></div><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div dir="ltr"><pre><font face="arial, helvetica, sans-serif">Jonathan Vigh
