On Mac:
Execute the installer by double clicking the Install icon.

The installer should start with the following window:

If you get an error message, it is probably due to an invalid Tcl/Tk version, check with your system manager.
The Next button at the bottom right part of the window will be green when the installer is be ready to move to the next step.
Note: on Mac, Tcl/Tk can't properly allocate colors to buttons.

Read the text and press the Next button.

Select the most recent version and click Ok. On UNIX systems, the non versioned executable is generally a link to the latest version and therefore should be the one to select. For example if the latest Tcl/Tk version is 8.3, then the /usr/local/bin/tclsh file is often a link to /usr/local/bin/tclsh8.3 executable. To check this, type in the shell: file /usr/local/bin/tclsh the response will tell if it is a link and to which file. In this figure, the file /nfs/ozone/pdb/IRIXbin/tclsh is a symbolic link to the file /nfs/ozone/pdb/IRIXbin/tclsh8.3 and therefore will be selected as the default Tcl commands interpreter.

On Mac, you just need to select the 'Drag and Drop Tclets' application located in the Tcl/Tk installation folder:

Be sure to pick the right application.
'Drag and Drop Tclets' () is found in the 'Build' sub-folder:

Once completed, press the Next button.

The selection represents all valid pathways where programs can be installed. Select the most appropriate path and click Ok.

Once completed, press the Next button.

If RmscopII was already installed, the installer will display its location and you will be asked to select which one needs to be replaced. Ideally, only one copy should be found. If more than one copy is shown, the first one is most likely to be the one used from the shell command line. To know which copy is used from the command line, type in a UNIX shell:

On Mac, the 'Drag and Drop Tclets' selected in the previous step will be used to generated the RmscopII 'executable'. Click on the proceed button to perform the action:

Read carefully: if the 'Drag and Drop Tclets' is used for the first time, the program will ask you (check message on top left side of the screen) to 'Select "Wish" stub to clone'. Use the file browser to select the 'Wish' application located in the Tcl/Tk folder: Once selected the 'Wish' application, click on Ok and the normal procedure will continue. The 'Drag and Drop Tclets' is now asking where to store the RmscopII application. In theory, you could store it wherever you want with the name you prefer. In practice, I would recommend to store it as 'rmscop2' application in the RmscopII folder. An icon like this one will be created:

Shells and browsers interface:

On UNIX systems, a shell script called rmscop2 will be generated in the same directory the RmscopII script is installed.
On MSWin systems, a batch file called rmscop2.bat will be generated in the same directory the RmscopII script is installed.
On Mac, an AppleScript called Rmscop2Droplet is provided with the package.

For UNIX and MSWin, be sure to have write permision for the selected path otherwise ask your system administrator to perform the installation.
Click on the Yes button to peform the installation of RmscopII.

The rmscop2/rmscop2.bat file installed with the RmscopII Tcl/Tk script is the one to be used to start RmscopII as it will have all the information to run the program properly.

On UNIX, you'll call RmscopII by typing in a shell:

On MSWin, you'll call RmscopII either by typing in a DOS shell:

On Mac, you start can start RmscopII by double clicking on the rmscop2 executable icon:

The Rmscop2Droplet provided with the package as:

allows to drag and drop PDB files or RasMol scripts on it and to integrate RmscopII with the web browsers (see the Documentation page for more info).
The Installer will execute the Rmscop2Droplet after you click on the Proceed button. A window like this will be shown:

Use the Set RmscopII path button to pick the RmscopII application you just created previously. Once completed click on the Done button. Now the Rmscop2Droplet will be able to execute RmscopII whenever needed. To change the path later on, just double click on the Rmscop2Droplet.

Once completed, press the Next button.

If the PDB system variable is defined, it will be automatically used as proposal. If you don't have a local copy of PDB, specify a location where new PDB files will be stored after download.

Next, you'll need to select a cache directory that will be used to store temporary files. If you don't have a local copy of PDB, use the same directory as the one defined above. Click Ok when completed.

Once completed, press the Next button.
