This issue is likely because the tool is unable to render the data preview due to its size or format, which prevents you from moving forward.
Here are some steps you can take to solve this issue:
- Check Data size: If your dataset is too large, try reducing its size by filtering or preprocessing it before loading it into ntstool.
- Data Format: Make sure your data is in a compatible format that ntstool can process (such as CSV, Excel, or other supported formats).
- Increase Java Heap Memory: In MATLAB, you can increase the Java heap space by going to Preferences > MATLAB > General > Java Heap Memory and increase the allocation.
- Subset of Data: Consider splitting your data into smaller chunks and processing them individually.
