Pulse sequence drawing

Introduction

NMRWiki can produce pulse sequence images from plain text. Pulse sequence markup should be surrounded by <pulse> </pulse> tags.

The new pulse sequence markup is intended to be easily readable and being able to provide detailed input of NMR pulse sequences for display as images and in the future - produce real pulse sequence code.

The manual will appear gradually. Current version is experimental - please report any bugs/problems (here).

At this time errors are not displayed to the user, so if something is incorrect there will be no easy way to tell how to fix the problem. This will be fixed soon, so please come back!

Code

Here is the markup that produced the image above
