TREX developers have prepared a number of "TREX Tools" and set-up guides. Development of these tools and guides were an outgrowth of research projects and efforts to share TREX with new users. Many of these guides were created to answer detailed questions about model use and parameterization.

A list of tools and set-up guides is presented below. These TREX Tools and set-up guides are not typically shared with every user. The frequency of software changes and updates is so rapid that the TREX development team does not often revise and update these tools. When these tools are shared, the decision to do so is made on a case-by-case basis.

Contact the developers for information about the availablity of TREX Tools and set-up guides through the Contacts link.

Notice: TREX Tools and model set-up guides distributed in the hope that they might be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Users granted access to any TREX tool or guide should expect that software and web sites for data acquisition have changed and that programs must be modified before use.
