How to insert an image into a post in Biostars? There is a image icon above. BTW, how to display codes tidily (like markdown but not html)? I cannot find a readme or manual or else about it in Biostars. Thank you.
You need to have an image hosted on a different website such as imgur then click on the Image icon between the Anchor (flag icon) and Table (boxes icon). Markdown is not yet supported but will be rolled out eventually, its been added to the new version of biostars: https://github.com/ialbert/biostar-central/issues/227#issuecomment-75310605
BioStars uses a subset of CommonMark, there is a list of commands here.
blocks of code enclosing the code with three back-ticks do not work
three back-ticks turn out the same as one back-tick, for inline code
# But blocks of code with four spaces preceding do: print "\n";
Some possibilities (like adding a heading):
A numbered list:
_italic_ __bold__ (display correctly on preview, but not when posted)
italic again bold again
An horizontal rule
An unordered list
One thing which didn't work is formatting a numbered list with parentheses:
1) One 2) Two 3) Three
