Error when run "preprocess_dannce(filename_in,filename_out,species_name,'')" about dannce HOT 5 CLOSED

Hi Yuan,

You are right that the filtfilt was the problem. I added a simple masking in that section of the code (in the CAPTURE repo) to address this. I pushed the change to the capture demo and included the fix below. Did this work?

frames_to_mask = union(find(isnan(marker_velocity(ll,:,4))),find(isinf(marker_velocity(ll,:,4))));
marker_velocity(ll,frames_to_mask,4) = 0;
abs_velocity_antialiased(ll,:) = filtfilt(f1,f2, marker_velocity(ll,:,4));
marker_velocity(ll,frames_to_mask,4) = nan;
abs_velocity_antialiased(ll,frames_to_mask) = nan;

Can you please describe in more detail what exactly you are trying to run (i.e. the exact command) and with what data? and what version of Matlab are you using?

Hi, thank you very much for your reply!!
i just try to run the script of preprocess_dannce.mat as the demo page shows:

filename_in = 'predictions.mat';
filename_out = 'predictions_preprocessed.mat';
species_name = 'mouse'
preprocess_dannce(filename_in,filename_out,species_name, ' ')

the error is reported as below:

i think it is cased by the calculation of abs_velocity_antialiased value as it has infinite values.
So i wonder whether it is possible to ask how to fix the issue of infinite values? or is there any suggestions? thank you so so much for all!!! @spoonsso
