[MSNoise] the stretching method problem

Dear MSNoise users, Although my cross-correlation functions (CCF) are relatively symmetrical, they have different positive and negative lag-time (left and right side). When I used the MSNoise for the stretching method, my results for different dtt_sides (both sides, right side, and left side) are exactly the same, while they should have different results. So, do you know how can I fix this problem? Sincerely, Navid
