(2003) Estimating Health Expectancies from Cross-longitudinal surveys. <em>Mathematical Population Studies</em>.- 10(4), pp. 211-248</a> </p> <h2><font color="#EC5E5E"><strong>Download and instructions for installation</strong></font></h2> <h3>On Windows (win9X, 2000, XP)</h3> <p> Until June 2004 the installation did consist in a zip file which had to be extracted in the directory of your choice. But with version 0.97b IMaCh we are using a windows installer (Inno setup). Both executables <tt>imach.exe</tt> and <tt>gnuplot.exe</tt> (the grapher that we are using) have to be on the same directory. <br> In order to facilitate the use of IMaCh we associated the .imach extension to two features: editing and running. Thus by right clicking on a foo.imach file you can either 'edit'the file (default) with the notepad editor or 'run' it with gnuplot (you need a recent version).<br> But we discovered that on some computers, people are not allowed to modify the windows registry and need to have Administrator privileges. <br> Thus we built two windows installer: a standard setup which will install the progam (usually in <tt>\Program Files\imach</tt> and will modify the registry to associate <tt>.imach</tt> extension to notepad and imach, and a second which will not alter the registry. With this second installer you will be able to install the programs in your home directory and run it by clicking on the imach.exe icon. But you won't be able to use the facility of the right clicking. </p> <ul> <li>Download latest <font size="2" face="Courier New"><strong>imach-0.97b-setup.exe</strong></font> and execute it .</li> <li>Different sub-directories are created: <ul> <li>doc: most of the documentation. The main document is <a href="doc/imach.htm">doc/imach.htm</a> .</li> <ul> Here are also two data files:<font size="4" face="Times New Roman"> </font><ul> <li><font face="Courier New">data1.txt</font> which is the main data file on which the program has been run as the example in the main documentation.</li> <li><font face="Courier New">mydata.txt </font>a smaller data file which you can use for your own trial.</li> </ul> </ul> <li>bin: <ul> <li><font face="Courier">imach.exe</font> the executable for Windows 95/98/NT compiled with gcc from cygwin.</li> <li> gnuplot, the grapher use by IMaCh. Its reference manual and sources can be accessed from <a href="http://www.gnuplot.info/">http://www.gnuplot.info/</a>. </ul> </li> <li>src: This subdirectory contains the source of the program. It can be obtained by asking us by mail <a href="mailto:brouard@ined.fr">mailto:brouard@ined.fr</a> and <a href="mailto:lievre@ined.fr">mailto:lievre@ined.fr</a> .</li> </ul> </li> <li>Right click on the .imach to either edit it or execute it with Imach.</li> <li>Read the file README.txt or, better, click on <a href="doc/imach.htm">doc/imach.htm</a></li> </ul> <br> Imach version 0.97b of June 21 2004 can be downloaded as a setup.exe file <a href=imach-0.97b-2-setup.exe"> http://euroreves.ined.fr/imach/imach-0.97b-2-setup.exe</a>. The IMaCh program and gnuplot will be installed in the directory that you want (usually in Program Files). We made some errors in the new setup and some erlier versions did not work. Please check the md5sum which is 3cb42bf71396d531d4bc3d42fee46a52 imach-0.97b-2-setup.exe <br>We also changed the wordpad editor to notepad which is less useful but exists on most Windows installation. <br> For people who are not allowed to modify the registry of their Windows installation here is a second setup <a href="imach-0.97b-2-noreg-setup.exe">imach-0.97b-2-noreg-setup.exe</a>. <p><a href="oldversions.html">Old Windows versions are accessible here.</a> <h3>On Mac OS/X</h3> IMaCh can be easily compiled with gcc 3.3 on MacIntosh as soon as XCode (free download from Apple) is intalled on your MaCIntosh.<p> It take a litle more time to get latest version of Gnuplot 4.0 for Mac OS/X and to compile it on a MaC. The main problem resides in finding the png library. Gif images are patented now and the replacement is png, but the development of the png library is growing on its own and you just have to find on Google where it is hosted now. <br> Gnuplot can be easily compiled on a MaC, but I don't know yet (July 2004) which is default screen terminal driver for gnuplot. For sure if X11 is installed on your MaC (it is included on your installation CD or you can download it from the WEB), the you can do <tt>set ter X11</tt> and <tt>plot sin(x)</tt> to get a nice sin curve on an X11 window of your Mac. <br> Let me add that for running IMaCh with all of its features, you don't need X11; the gnuplot program included in the distribution needs only to have the png terminal driver to output graphs and these graphs will be viewed by your browser.<br> You need X11 only if you want to modify and test the gnuplot code output by ImaCh, because it might be a more convenient way to view the graphs directly on the screen than writing images on a file and viewing them with a browser, <p> You can download a .pkg.pax file at <a href="imach097b.pkg.pax">imach097b.pkg.pax</a>. Stuffit Expander will expand the compressed file into a imach097b.pkg directory. Just clicking on the directory will let you install IMaCh in a local directory of your own (you have to create a new folder name IMaCh097b or whatever). Two sub-directories are created <tt>bin</tt> and <tt>html</tt> . In the bin subdirectory you will find two executables <tt>imach</tt> itself and <tt>gnuplot</tt>. <p> You need to click on <tt>imach</tt> and IMaCh will be launched in a terminal window, asking you to enter a <tt>parameter</tt> file. A parameter file is text file with an extension <tt>.imach</tt> (but you can use a <tt>.txt</tt> extension if you want. Among the parameters required, a data file name has to be entered. It can be a relative file name like <tt>../../data/data1.txt</tt>. It might also work if you use the Windows backslash "<tt>\</tt>" syntax. <p> At the end of the run, and it order for the terminal window not to disappear, the program will prompt for a command like "<tt>e</tt>" for edit or "<tt>q</tt>" for quit. The edit command might not work on a MaC, or on Unix or even on recent Windows, because the program should know which browser you are using and becauee the BROWSER environment doesn't seem to be standard on a Mac and on some other OS too. <br> The consequence for you is just that you have to use your finder or browser (there is no more difference now) and click on the <tt>.html</tt> (or .htm) file created. The filename of this html file is the same name as your parameter file, only the extension .imach is changed to .html. <h3>On Linux</h3> There are various versions of Linux, gnuplot is distributed on most distributions. Just verify that your version of gnuplot is more recent than version 0.38i . I haven't had time to make a rpm yet, just ask us for the CVS tree location (not completely GPL today), and compile the sources. Remarks concerning the Linux versions are similar to the Mac OS/X version. A binary rpm will be given as soon as a src rpm will be given which means that the whole program will be GPL licensed. <p><a href="doc/imach.htm"><font color="#FF0000" size="6">Click here to access to the detailed documentation</font></a></p> <p>This software have been partly granted by <a href="http://euroreves.ined.fr">Euro-REVES</a>, a concerted action from the European Union.
