Problem with assigning node names to a directed graph

I'm trying to add the node names to a directed graph. I used the following code:

load network.mat network;
load node_names.mat node_names;
graph=digraph(network,node_names,'omitselfloops');

network is the adjacency matrix (63x63 double) and node_names is the array with the node names (63x1 cell).

Now, when I try to create the graph with the node names, matlab tells me:

Error using digraph>validateFlag (line 643). Option must be 'omitselfloops'.

Error in digraph (line 253) omitLoops = validateFlag(nnames, omitLoops);

I have no idea what's wrong with my code.

I solved it! I don't know why it didn't work before, but I used the following code:

graph.Nodes = node_names
