Rachel is written in Python 2.6 and is expected to be Python 2.7 compliant. It runs under Linux and Unix (OS X) machines. A Windows version is not planned. |

| + | A 64-bit processor is essential, because Gosia runs fastest and most accurately on 64-bit machines. Versions 1.* have many structural changes in the code, allowing more automation, more general particle detector options and fewer user prompts for standard operations. | ||
[[File:Typicalgosiainput.png|thumb|right|Excerpt of a typical Gosia input for a collective system.]]While gosia.20081208 incorporates the [[OP,BRIC]] command to read internal conversion data from BrIcc data files, removing the burden of entering ICC interpolation data by the user, the GUI allows the greatest possible automation by prompts for pre-defined or user-defined germanium detector crystals or arrays, calculation of Zeigler stopping power data, optimum meshpoint selection for yield calculations, transformation of rectilinear detector definition to laboratory-frame spherical-polar interpolation coordinates, etc. For standard problems, the burden on the user is reduced to entering nuclear level and matrix data for simulations (including optional data-set simulation) and real experimental data for fitting of matrix elements. For collective systems, where the matrix definition often includes several hundred lines of matrix elements, rotor parameters can be given to reduce the setup time for the initial guesses of matrix element values. This also eliminates the need for the user to re-index the reduced matrix elements by hand as changes are made to the matrix or level scheme. | [[File:Typicalgosiainput.png|thumb|right|Excerpt of a typical Gosia input for a collective system.]]While gosia.20081208 incorporates the [[OP,BRIC]] command to read internal conversion data from BrIcc data files, removing the burden of entering ICC interpolation data by the user, the GUI allows the greatest possible automation by prompts for pre-defined or user-defined germanium detector crystals or arrays, calculation of Zeigler stopping power data, optimum meshpoint selection for yield calculations, transformation of rectilinear detector definition to laboratory-frame spherical-polar interpolation coordinates, etc. For standard problems, the burden on the user is reduced to entering nuclear level and matrix data for simulations (including optional data-set simulation) and real experimental data for fitting of matrix elements.

| - | When | + | When changing to version 1.0 or later, users will have to rebuild their sessions, because of major changes in the internal structure that cannot be automatically upgraded. This can be aided by the export/import tools for the level and matrix data. Subsequent versions will have the automatic upgrading reinstated. |
| - | + | ==Graphics Issues== | |
| - | + | If you do not see a level scheme diagram after loading a level scheme or a saved session, click "Examine fig. window" once. The level scheme should then appear. | |
| + | If it does not, or if the level scheme window buttons (zoom, pan, etc.) do not work, you may need to change the graphics back-end. The matplotlib graphics library used for the level scheme and particle detector layout comes with several choices of back-ends. | ||
| + | |||
| + | *On OS X machines, "macosx" may work best. | ||
| + | *On Ubuntu, GTKAgg works best, but the user must click "Examine fig. window" 'once' after loading a level scheme or saved session. | ||
| + | |||
| + | The back-end is in the matplotlibrc file in the .matplotlib directory, or will be, after you start Rachel for the first time. | ||
