Throughput Calculation Error

See original GitHub issue


i’m running into the following error. It seems that the generated image size is too big.

[2020-09-24 12:51:12 ERROR] Writing file for ThroughputCalculator failed with a fatal error. Attempting to run subsequent writers regardless.

ValueError: Image size of 15443364x1476 pixels is too large. It must be less than 2^16 in each direction.

Did this happen in the past? Is there an easy way of solving it?
