Some months have passed since I started working a new version of the Eikonal model. Creating a computational model to solve a biological question has many steps. First it is important to understand the problem at hand. If you don’t have too much experience in the subject, it might take some effort and time to get familiarized with the field. It is important to understand the biological issues but also the previous computational attempts to solve the problem. In my case, it took approximately three months to get comfortable when reading papers related to my project. It can be overwhelming at the beginning but later it significantly facilitates the rest of the work.
