Locking Node Positions

[Kurt Ebeling]

Hi,

I am trying to fix the x and y positioning of nodes such that any edits to the existing network do not alter the positioning of nodes (e.g. merging two networks, making stylistic edits to nodes and edges, adding nodes, etc.)

Is there a way to lock the positioning of each node on the network, so that the Cytoscape layout algorithm doesn't alter their positioning?

Thanks,

Kurt

Kurt –

 

There isn’t a locking mechanism per-se … but some layouts (e.g., circular and hierarchical) will allow you to lay out only selected nodes. This isn’t the same thing, but may get you where you need to go.

 

Thinking further on this, for the unlocked nodes, how do you think they should interact with the fixed nodes during a layout? For example, suppose a circular layout, lock all node positions, and then add a node. Where would the new node be positioned after the layout?

Hi Kurt,
    Sure, go to the Style panel and under Properties, select X position and Y position.  Then select the node you want to fix the position of and enter the position as an override in the "Byp." column for the X and Y positions.  From my testing, that will override any layout.

Thanks Scooter!

It's tedious, but it works!

I'm trying to do this but can't, for one trivial reason and one non-trivial reason. Trivial: If I choose the Style panel before selecting the node, the Style panel collapses when I choose the node. Nontrivial: The Bypass dialogue ("Node Y Location", for example) asks for a number, but I have no way of knowing what that number should be, so I don't know what to enter. Please help.

While we're at it, in the Style panel my X Location's 'Map.' column is blank and X Location has no Column or Mapping Type or values, but my Y Location's 'Map.' column has a 6-dot grid and has a Column and Mapping Type and several values. Is this difference germane to my wanting to lock/fix a node's position, and if so how should I proceed?

Thanks.

I haven't seen that before, and it certainly shouldn't collapse.  Can you send us a screenshot?

Well, that will take some trial and error.    Generally speaking, if nothing has changed, 0,0 should be in the middle of the screen, negative X is to the left and negative Y is up.

That means there is a mapping for the Y values.  You can always override any mapping by putting a value in the Bypass column.
