Another interesting possibility is to try some imputation scheme (see https://en.wikipedia.org/wiki/Imputation_(statistics) ) . This is common in many machine learning applications, but I don't know if anyone has tried it for vbSPT.

Hi! vbSPT cannot handle missing positions, unfortunately. It can however handle a large number of trajectories, so one way forward might be to split up your data and analyse the stretches between missing values as distinct, independent trajectories. In that case, it might also be a good idea enforce a lower limit on the trajectory length and discard anything with less than, say 5-10 points (experimetns with simulated data might help you choose). If you are able to supply a localisation uncertainty...

Hello, I am working with data which contains gaps (from UTrack). A particle may disappear/be lost for a few frames then reappear. In the track data, the missing frames are represented as NaN values. However, vbSPT seems like it is not able to handle this format. I receive the warning dialogue: "the script could not run. Please check that the input data and trajectory field are correctly assigned." Could vbSPT handle gaps with another format? Thank you, Jaime

Dear Asok, it is difficult to say just form that. Could you provid a little more detail, for example about what is the content of the hmm struct? Best, Martin

Dear Martin, Thanks for answering and solving my last question regarding 'arrow.m' This time I was trying to use 'visualize_localisation.m' and it gave me the following error message: visualize_localisation Read options structure based on runinput file runinput_normal.m Undefined variable "hmm" or class "hmm.Wbest". Error in visualize_localisation (line 14) W=hmm.Wbest; Please Help me!! Thanks and regards

Dear Alok, I think the problem might be that arrow.m is an old version that is not compatible with your matlab versions, see https://se.mathworks.com/matlabcentral/answers/230792-why-does-arrow-fail-r2015a Please try to update Tools/displayHMMmodel/private/arrow.m in vbSPT with the latest version from https://se.mathworks.com/matlabcentral/fileexchange/278-arrow and see if that helps. Best regards, Martin

When I tried to run the program: VB3_displayHMMmodel('runinput_normal.m') Undefined operator '*' for input arguments of type 'matlab.graphics.axis.Axes'. Error in arrow (line 423) ax = 0 * gca; Error in VB3_displayHMMmodel (line 199) arrow(stateCoord1, stateCoord2, 'wid', round(transitions(1, 2)*100)); Please Help, I am using MATLAB 2016b and 2019b
