# Generate a graph of the high-scoring neighborhood of a single Rfam family.
# This script does not check parameters before using them. This is mostly
# because no operation writes or deletes anything. All results go to stdout!

# The following parameters are required:
# 1. directory containing Rfam models
# 2. model for which neighbors are to be generated
# 3. number of edges to generate
# x. input is stdin, with (1) model name (2) model name (3) score

# Everything is then wrapped for graphviz dot output:
# zcat rfam-weakpairs.gz | NeighborGraph.sh ../Rfam RF00943 10 | circo -Tps > graph.ps
