Image Artist: Batch Analysis Jobs Fail Due to Analysis Sequence Incompatibility

Problem

Batch Analysis jobs fail with the following error message in the Image Artist Job Status page:

Evaluation Aborted at Building Block Input Image Text: The analysis sequence has become incompatible with the selected input data.

Cause

This error occurs when the analysis script is not compatible with the dataset it’s being applied to.
A common example is when the script references a channel that does not exist in the dataset.

Resolution

To resolve the issue:

1. Open the dataset in question using the Image Analysis view in Image Artist.
2. Load the analysis sequence you intended to use.
3. Step through the sequence, ensuring each building block loads properly.
   • Modify any building blocks that are incompatible with the dataset (e.g., reference to missing channels).
4. Continue until you reach the Define Results building block.
5. Re-save the updated analysis sequence to the database.
6. For future Batch Analysis runs, use this updated script version.

Always verify compatibility between datasets and analysis sequences before submitting Batch Analysis jobs to avoid this type of error.
