make_fila!(c::Context;
    type=1,
    mono_states,
    node_mids,
    node_positions,
)::Tag{FilaTipIdx}

Return the tag of the plus tip of the new filament. Error if the filament isn’t initially over 2 monomers long. Newly added filaments can’t be selected from nearby monomers until after minimization.

Keyword Arguments

  • type=1: filament type id or symbol.

  • mono_states: Collection of the MonomerState or Symbol of the monomers in the new filament. In order from minus end to plus end. length(mono_states)>1

  • node_positions: Collection of SVector{3,Float64}. The positions of the nodes, monomers are between nodes.

  • node_mids: Collection of Integer. The monomer ids at (slightly plus side of) the node_positions | ––-+––-|––-+––- minus end <–– M | M | (M) | M ––> plus end ––-+––-|––-+––- | ^ A node_position is indicated by the line.

    The monomer id with parenthesis (M) will in node_mids length(node_mids) == length(node_positions) - 1

  • minus_end_mat_dir=nothing: SVector{3,Float64}. The mat direction of the minus end node.

  • joint_twists=nothing: Collection ofFloat64`. The extra material frame axial rotation at the joints between the cylinders.

  • tip_load_forces=(0.0=>0.0): tip load forces, usually don’t use this, because load forces will automatically get updated at the next minimization.
