I have an ''ses'' file of 1x144000 size. I converted them into 400x720 arrays with 200 overlap with the code "buffer". Based on this information, I calculated a value (feature) called mean crossing irregularity and this is a 1x720 size file. Based on this calculation, I set the threshold as 0.4. I have created a table with the ones larger than 0.4 as "non-wheeze" and the smaller ones as "wheeze". My aim is to find the indexes of these "wheezes" and mark the "wheezes" in the ''ses'' file with vertical lines, but I cannot find the indexes and therefore I cannot mark them. You can see the codes for all of the calculations and the table of marking wheezes and non-wheezes. Can you help me?
