Q: How do I uncompress a .zip or .tgz or .tar.gz file?

A:  The most popular decompression software for Windows is WinZip, a commercial product with a free evaluation version. 7-zip and FreeZip are freeware alternatives. 

Once you have installed one of these tools, sayWinZip, you can right-click on a .zip file to get a WinZip menu. From there you can specify where you want to extract the files.

If you're unzipping a .tar or related file, you may get a dialog saying your archive contains one file and asking whether to decompress and open it. Say yes and continue.

Note that you must unzip the .zip file before running the installer. Windows XP will let you navigate into a .zip from the File Explorer without first unzipping it. This will let you see the installer, but you cannot run it from there.

On Unix, the unzip command uncompresses .zip files. For .tgz or .tar.gz files, first use gunzip or gzip -d to remove the compression, then use tar -xvf to unpack the resulting .tar ball.

 

Q: Windows won't let me unzip my zip file. What can I do?

Windows XP Service Pack 2 locks down the decompression program that comes with Windows so that it cannot be used to unzip files downloaded from the internet due to security settings. The simplest solution is to install one of the third-party decompression utilities mentioned above, such as WinZip.

 

Q: Why are some products .exe files? Can I get a .zip file?

A: Because of the difficulties some users have with zip files, as mentioned above, we are starting to distribute our software as self-extracting executable files. Most users find this format more convenient. However, if you are unable to download executable files, please contact us requesting a zip file.

 

Q:  I double-click on my application and all I get is a flash. What happened?

A: If you double-click on the icon for a command line application, the program runs with no arguments. It does its job and goes away. This is the expected behavior if you run the application from the command line, but can be a surprise if you run it expecting Windows program behavior.

The solution is to open a command window then change directories to the location of the program. You can open a command window by going to Programs -> Accessories -> Command Prompt, or you can click on the Start menu, select Run, then type cmd in the edit box.

The CmdHere utility from Microsoft provides a convenient shortcut for opening command windows. Once it is installed, you can right-click on a folder in the File Explorer and select "CMD Prompt Here" to open a command window with that folder as the working directory.

 

Q: What tools do you use to develop your software?

The pattern for our newer software development is to use C# for the user interface and C++ for the numerical kernel. Most of the older software on this site was developed using fortran. See our resources page for more details.

This site was developed using ASP.NET, C#, and SQL Server 2000. We use FeedSpring to maintain our RSS feed.

 

Q: Why do you enter your email when you download software?

A: So that we can notify users of bug fixes and upgrades.

 

Q: Can I be notified when new products are available?

A: Yes, you can subscribe to our RSS feed to receive software product announcements and other news. If you do not use RSS, you may visit our web log periodically.

 

Q: What is RSS?

A: RSS stands for "Really Simple Syndication". It is a way of receiving notifications and summaries when items change on a web site. You will need a reader to subscribe to RSS. There are many free RSS readers out there. For a list of available readers and other RSS resources, see the RSS Compendium. For Windows, you may want to try Feedreader. On Macintosh, RSS support is built into the Safari browser.

The way you subscribe to an RSS feed depends on your reader. For Feedreader, you go to the File menu and selected New Feed. Then past the RSS address from your browser into the edit box that appears. Then click "OK".

 

Q:  Why do some products come with source code while others do not?

A: Many of the products on the download site are distributed as source code. Other products, due to their complexity and dependence on third party components, are distributed as compiled applications.

 

Q:  How do I cite software in a publication?

A:  Here's an example following the AMA Manual of Style to cite EffTox 2.10.

EffTox. Version 2.10. Houston, TX: Department of Biostatistics, The University of Texas M D Anderson Cancer Center; 2006.

Italicize the name of the software; use periods after the software name and version number; use a colon after the state, and a semi-colon before the year of development/manufacture/publication.

 

Q: My question is not here. What can I do?

A: Please send us an email.
