 This is a python implementation of the facetnet algorithm presented in
 [Lin, Yu-Ru, et al. "Facetnet: a framework for analyzing communities and their evolutions in dynamic networks." Proceedings of the 17th international conference on World Wide Web. ACM, 2008.](https://doi.org/10.1145/1367497.1367590)
 based on the implementation of [blmoistawinde](https://github.com/blmoistawinde/facetnet-python). References in code comments refer to paragraphs in this paper.
 
 == File description ==
 
-# //facetnet_step.py//: performs one time step update of the algorithm. Needs the state of the previous step as an input (*xcap.dat*, *lcap.dat*, *idmap.dat*, *idmap_inv.dat*). If no previous state is supplied, an initialization step is performed with alpha = 1.
+# //facetnet_step.py//: performs one time step update of the algorithm. Needs the state of the previous step as an input (`xcap.dat`, `lcap.dat`, `idmap.dat`, `idmap_inv.dat`). If no previous state is supplied, an initialization step is performed with alpha = 1.
 # //facetnet_evol.py//: generates an entire evolution of facetnet given a set of edge lists for different snapshot networks.
 # //facetnet.py//: python module implementing the algorithm
 # //facetnet_exp_4_1_1.py//: reproduces the experiment described in paragraph 4.1.1 of the original paper.
 # //paper_experiments/synthetic_dataset_1/0.edgelist//: edgelist for the static graph used for the experiment described before. This file also serves as an example for the input format of edge lists.
 
 The first two scripts can be called from the command line. Type e.g. `python3 facetnet_step.py --help` for a description of the arguments.
