Error while loading a big file with Cytoscape
The first thing you can try is to separate the network from the meta information. Assuming you have access to a *nix machine, you can run:

awk -F"," '{print $2,$4}' file.csv &gt; network.csv


That will produce a file like this (based on your example data):

test1 test2
test11 test12
test12 test22


That should radically decrease the file size and will give you the best chance of loading it in Cytoscape. You can then similarly extract the attributes:

awk -F"," '{print $2,$1}' file.csv &gt; source.column1.attributes
awk -F"," '{print $2,$3}' file.csv &gt; source.column3.attributes
awk -F"," '{print $4,$5}' file.csv &gt; target.column5.attributes
awk -F"," '{print $4,$6}' file.csv &gt; target.column6.attributes
awk -F"," '{print $4,$7}' file.csv &gt; target.column7.attributes
awk -F',' '{print $2,$4,$8}' file.csv &gt; edge.column8.attributes
awk -F',' '{print $2,$4,$9}' file.csv &gt; edge.column9.attributes
awk -F',' '{print $2,$4,$10}' file.csv &gt; edge.column10.attributes
awk -F',' '{print $2,$4,$11}' file.csv &gt; edge.column11.attributes
awk -F',' '{print $2,$4,$12}' file.csv &gt; edge.column12.attributes
awk -F',' '{print $2,$4,$13}' file.csv &gt; edge.column13.attributes
awk -F',' '{print $2,$4,$14}' file.csv &gt; edge.column14.attributes


Now, try loading network.csv into Cytoscape and then load each of the node and edge attributes separately. 



However, a network with 200,000 nodes and 230,000 edges is just too large to be able to manipulate in any useful way in a GUI. It will just look like a horrible hairball. I really urge you to do some preprocessing and pare the network down to something more manageable. I used to work with a human PPI network of ~13000 nodes and ~15000 edges. While I could load that into Cytoscape, that was already far too big to be able to do anything useful with. I could use the data analysis aspects of Cytoscape, but not really the visualization.
