Here I present a simplified version of the workflow used in Bedriñana-Romano, L., Hucke-Gaete, R., Viddi, F.A., Johnson,D., Zerbini, A.N., Morales, J., Mate, B., Palacios, D.M., 2021.Defining priority areas for blue whale conservation and investigating overlap with vessel traffic in Chilean Patagonia,using a fast-fitting movement model. Scientific Reports 11, 2709.The model presented here is a continuous-time correlated random-walk model, originally developed by Devin Johnson (Johnson, D.S., London, J.M., Lea, M.-A., Durban, J.W., 2008. Continuous-time correlated random walk model for animal telemetry data. Ecology 89, 1208-1215.) and modified to allow the incorporation of covariates modulating the main movement parameters
