PoreXpert features a very comprehensive help and tutorial system. It is in the form of a User Manual that is directly accessible from this website.
The Manual also provides context-sensitive help supplied with the PoreXpert software, accessed by clicking the button on the screen you are using or clicking your F1 key when using a particular PoreXpert screen.
When you are using the PoreXpert software, the context-sensitive help system accesses the relevant website page if you are online, as that is likely to be more up to date, particularly with regard to tutorials.
The User Manual is also available as a pdf from the downloads section and provided as a bound paper copy on purchase of the software.
