= Using the CBU imaging wiki =
This wiki contains the collected and sometimes rather old recorded CBU wisdom about imaging. It is almost completely devoted to FMRI, and has a large bias towards StatisticalParametricMapping software, just because that is what we all use.

== Reporting problems ==
If you see anything that is wrong, broken, silly or annoying, please contact the ImagersWikiAdmins, who take care of the wiki.

== Some pages are restricted to users with approved login names ==

Most of the pages here are publicly readable, but you will need to have an approved login to read some pages. If you try to read such a page, and are not logged in, or have an login that is not approved, then you will get a message - "You are not allowed to view this page."

[[Anchor(login)]]
To get an approved login, see the instructions on the base wiki: CbuBaseWiki:GettingApproval.

If you want edit permissions or want to see internal pages, please email one of the ImagersWikiAdmins with your login name.  If you want CBU or Cambridge permissions, please let us know your affiliation. We will then add you to the necessary lists.

== Making home pages ==

Please see CbuBaseWiki:MakingHomePages

== Configuring the wiki to your taste ==

See HelpOnUserPreferences - and make changes in your UserPreferences.  Note that, if you like your text to be a bit smaller than the current wiki default, you can add `/wiki/cbuimaging/css/smaller.css` to the '''User CSS URL''' field of your UserPreferences. 

== Editing pages ==

You will need an approved login to edit pages. In general we welcome help with editing pages, so please ask if you want to edit.

If you make edits to a page, please sign your edits somewhere by leaving your login name, e.g. I just wrote this (MatthewBrett)

=== Adding images and attachments ===
is very easy. For example if you wanted to add an image, just insert the text {{{attachment:my_image.png}}}. When you have saved the page, you can click on the link to upload the image as an attachment to the page. See HelpOnLinking for more details.

=== Putting up documents that need access controls ===

Some of our pages and some of our documents need to be restricted to people with CBU logins, or Cambridge logins.  For pages that should be restricted to the CBU, add this as the first line in the page:

{{{
#acl GoodGroup:admin,read,write CbuGroup:read
}}}

and for Cambridge (and CBU) pages:

{{{
#acl CambridgeGoodGroup:admin,read,write CambridgeGroup:read
}}}

If you want to post documents with access controls, then attach them to a page with the access controls above, and the same access controls will apply. Don't link to the attachment directly, link to the page that has the attachment.  So, if the document is often linked to, you probably want a very small bare page containing the attachment to avoid confusion. An example is MriSubjectScreening. 

=== Making links when editing pages ===
Making links is covered in the HelpOnLinking page - but also you can also use the InterWiki facility in our wiki farm to link between different wikis - for example - [wiki:CbuMriFacility:CbuMriFacility CBU MRI facility]

This wiki has the InterWiki name of !CbuImaging, and the MRI wiki is !CbuMriFacility.

== Some advanced wiki features ==

=== Making a pdf from a wiki page ===

If you you want a pdf version of the page to print out, then append `?action=CreatePdfDocument` to the page URL.  You will get a form to set any options for pdf generation.  Click the button 'Generate PDF' at the bottom of this form to generate a pdf - e.g.

http://imaging.mrc-cbu.cam.ac.uk/imaging/UsingThisWiki?action=CreatePdfDocument

=== Using LaTeX expressions ===

For those of you who know what LaTeX is, you can also use LaTeX syntax to enter mathematical expressions - see eg:
