+# 0024_GRNCoopSW8_001
+
+a gene regulatory network of 100 genes connected according to a small-world topology, from the AGN suite
+
+## tests
+
+- 1D, 100 units, network, GRN
+- cps file reads well
+- network file reads well
+- named output file
+
+- checks the regulated_by_1 rate law was created
+- checks that there are exactly 3 species
+- checks that noise worked
+- checks no compartments created
+- checks that there are three synthesis reactions
