Frequently Asked Questions

Q: My cells are not initialized at the right position

This is possible due to the lattice spacing usually (unless defined otherwise) being 0.5 µm while the positions in the .pos file are in µm. This means that a cell center of 10 12 24 in a .pos file will have a center of 20 24 48 in the simulation.

Q: Can the cells lie out of the domain?

Yes, cells are bound inside the domain by their centerpoints, so parts of the cell might reach over the domain. These cells are deleted during initialisation, unless the system is run on a single core.

Q: What is the exact centerpoint of the domain, how big is my domain?

When you specify a domain of for example 10 cells, the exact middle will be BETWEEN cell 5 and 6. imagine that dx is 0.5µm then the domain is 9.5µm long, and the middle is 4.75µm. periodic boundaries of course add 1 dx back to the length.

Q: Compiling with the singularity images gives an error within Cmake

We have had reports that the clang (or llvm) compiler can cause problems with compiling the singularity image. Disabling it (removing it from the environment) or using another system might work. We are looking into this issue.

Q: Compiling with singularity gives errors

Maybe you have an old hemocell/ folder in the same directory and are trying to compile with a newer version. If this is the case you can rename hemocell/ to hemocell_old and the newer singularity image should create a new folder
