Gnuplot has evolved since version IMaCh 0.98k and therefore you need at least Gnuplot 4.6.5. Otherwise you need to adapt the .gp file produced in order to run with your old gnuplot. With the installer provided for OS/X and Windows, a recent gnuplot binary is provided and will be installed on the same directory that the IMaCh binary. It is better to use your own Gnuplot installation and IMaCh will test the command '''gnuplot''' but if the binary in not in your path, it will make a error but will use the binary provided by the installers. Using recent gnuplot installations, there is usually a possibility to add the gnuplot binary in your path. <h3>On Windows (XP, Vista, Windows 7, Windows 8)</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 0.98d and above IMaCh we are using a windows installer (Inno setup 5.5.5). <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> <br> You need to have the Administrator privileges to install the software. We don't propose anymore an installation which does not alter registry because we think that you all have access, even temporarly, to Administrator privileges (usally by right clicking the .exe you can choose "Install with Administrators privileges". </p> <ul> <li>Download latest <font size="2" face="Courier New"><strong>imach-0.98p0-ilc-setup.exe</strong></font> and execute it .</li> <li> Gnuplot is installed by default on Windows. But if you are using another Operating system: <ul> <li> Download <font size="2" face="Courier New"><strong>gnuplot</strong></font> 4.6.5 at <a href="http://www.gnuplot.info/">http://www.gnuplot.info/</a> ; at the end of the install it is asked if you want to have the gnuplot binary in your path, say yes.</li> </ul> <li>Different sub-directories are created: <ul> <li>doc: most of the documentation. The main document is <a href="wiki/index.php/Documentation">http://euroreves.ined.fr/imach/wiki/index.php/Documentation</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></li> <li> gnuplot, the grapher used 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 brouard at ined pointfr .</li> </ul> </li> <li>Right click on the .imach to either edit it or execute it with IMaCh. At the end of the program, IMaCh uses gnuplot to produce the graphs, then you can open your browser to read the main .htm file with all results and graphs. If gnuplot is not installed or not in your path, you have to run gnuplot on the ".gp" source file generated by imach. Using wgnuplot you have to "open" it. </li> <li>Read the file README.txt </ul> <br> Imach version 0.98p0 and 0.98q0 of March 2015 can be <a href="#Download">downloaded below</a> as a setup.exe file imach-0.98?-#-setup.exe. The ? corresponds to a version number while the # corresponds to same program but compiled differently. <br> After having tested crosscompilations from a Unix box we moved to native versions compiled with Visual Studio Express compiler 2013 32 and 64bit bits)</a> and, better, Intel C/C++ compiler from the package <a href="https://software.intel.com/en-us/c-compilers">Intel® Parallel Studio 2015</a> <ul> <li> On Windows 64bits, this Intel Compiler gives clearly quicker results because public domain C compilers, gcc, are not optimized for 64 bits OS yet. <li> On OS/X we use the native Apple C compiler derived from gcc because it gives better results. <li> On Linux, we use standard gcc. </ul>         The IMaCh program and gnuplot will be installed in the directory of your choice (usually in Program or Program Files). Please check the corresponding md5sum, if the download is corrupted. <br>After installation, a right click on a .imach file lets you edit with the notepad text editor (which is less useful than other text editor like workpad but which have the advantage to be installed on any Windows). <br>     <p><a href="oldversions.html">Old Windows versions are accessible here.</a> <h3>On Mac OS/X Lion and higher (March 2015)</h3> IMaCh can be easily compiled with gcc on MacIntosh as soon as XCode (free download from Apple) is intalled on your MaCIntosh.<p> It take a litle more time to get version of Gnuplot 4.6.5+ for Mac OS/X and to compile it on a MaC. Currently graphs are output as png files. We will probably moved to svg because the svg format is scalable and thus figures are easier to improve and to insert in other documents. <p> You can <a href="#Download">download below</a> a dmg file, for example imach0.98nX.dmg and install it. Like on Windows, 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>. With recent versions, this tree is embedded in an Application. <p> You need to click on <tt>imach</tt> application and IMaCh will be launched in a Terminal window, asking you to enter the name of a <tt>parameter</tt> file. A parameter file is a 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>. <br> If you open a new finder you can drag an IMaCh parameter file into the terminal IMaCh Window that you just created. <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 editing/viewing the results (with your browser) or "<tt>q</tt>" for quit. <br> You can use the finder or browser (there is no more difference now) and click on the main <tt>.html</tt> (or .htm) file created. The name of this main html file is the same name as your parameter file, only the extension .imach is changed to .html. If you slightly change the parameters, you just have to give another name and the new results will not override the former. <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 4.6.5 . 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. <p> <font color="#FF0000" size="3"><tt>New (March 2015)</tt></font> You can <a href="#Download">download below</a> a binary tar file for respectively a 32 bits or 64 bits Linux bo, for example: imach-Linux-0.98p0-linux-i586-bin.tar.bz2 and imach-Linux-0.98p0-linux-x86-64-bin.tar.bz2 <p> The binaries have been crosscompiled with gcc on my OS/X Mac. Each binary contains two directories <tt>bin</tt> and <tt>html/doc</tt> . In the bin subdirectory you will find the <tt>imach</tt> executable and in <tt>html/doc</tt> the <tt>biaspar.imach</tt> test parameter file and its corresponding data file <tt>data1.txt</tt>. In order to run the test the command is <tt>./bin/imach ./html/doc/biaspar.imach</tt> <p> <tt>gnuplot</tt> should be installed otherwise at the end of the run (optimization and calculations last at least 7 minutes on today most efficient hardwares) the command <tt>gnuplot biaspar.gp</tt> will fail. If successful, typing <tt>e</tt> will open <tt>biaspar.htm</tt> with your browser and all the results including graphs generated by gnuplot will appear.
