# see below for UPDATES that include more shorter ways of conversions

# How to convert GTF format into BED12 format (Human-hg19)?
# How to convert GTF or BED format into BIGBED format?
# Why BIGBED (If GTF or BED file is very large to upload in UCSC, you can use trackHubs. However trackHubs do not accept either of the formats. Therefore you would need bigBed format)

# First, download UCSC scripts
wget http://hgdownload.cse.ucsc.edu/admin/exe/linux.x86_64/gtfToGenePred
wget http://hgdownload.cse.ucsc.edu/admin/exe/linux.x86_64/genePredToBed
wget http://hgdownload.cse.ucsc.edu/admin/exe/linux.x86_64/bedToBigBed

A node-link diagram running a javascript implementation of the Dijkstra algorithm. Every time the visualization is refreshed two nodes are selected as start (in red) and end point (in blue). Then the shortest path is computed and shown on the diagram by highlighting the edges.

Just some notes and references for myself.

• In bash, you can access your C:\ drive via /mnt/c/
• ~ = C:\Users\MLM\AppData\Local\lxss\home\mlm and is different from your Windows user directory C:\Users\MLM
