• How should I set the optimisation range?
  Setting the optimisation range to a subset of the frames allows MoMA to perform optimisation faster. Hence it is desirable to use the largest optimisation range at which optimisation is still very fast (typically 150-300 frames). In datasets where a few consecutive frames are particularly problematic, it is useful to transiently set a very short optimisation range to fix these frames (since optimisation might be run many times).
• I got an error message "ILP unfeasible. Please reoptimize..." What should I do?
  This error happened because the constraint that you entered manually by setting a cell or an assignment can't be handled by MoMA. Before restarting the curation from scratch, it's worth resetting the corresponding frame and/or transition: this should bring you back to the state you were at before setting the faulty constraint.
• Does the segmentation result depend on the optimisation range that I set?
  In practice, one wants to use the largest optimisation range at which optimisation is still very fast (typically 150-300 frames). Of course, the optimal solution found by MoMA can be impacted by missing additional information contained in future frames (close to the end of the range). The only documented case where this is problematic is the analysis of very difficult datasets where the user relies on a very short optimisation range to produce a correct solution; when reloading the curation file, the optimal solution is likely to contain several mistakes since the results were checked with optimisation run a local subsets of the data...
