================
The files in this
directory are for installing the latest version 3.0.0 of AstroImageJ on Linux,
Windows, and Mac operating systems. The files are complete and do not require a
previous installation of ImageJ or AstroImageJ.
If you already have
installed version 2.0 of AIJ, simply use the update option on the AIJ toolbar
'Help' menu to upgrade to 3.0.0. The
user will need write permission to the directory where the software is
installed.
For more information
and help, please see the AstroImageJ user forum on nabble:
http://astroimagej.1065399.n5.nabble.com/
Once you have
installed this version, use the Update feature under the Help menu to install
the latest changes.
Linux Installation
==================
Download
AstroImageJ_3.0.0_20141206_linux.tar.gz
(provides AstroImageJ)
AstroImageJ_script.tar.gz (provides a startup script for AstroImageJ)
As root user
cd /usr/local
If you already have
AstroImageJ installed in /usr/local change
it to a backup name such as
mv
AstroImageJ AstroImageJ_old
Untar the archives
tar xvzf
AstroImageJ_3.0.0_20141206_linux.tar.gz
Untar the script "astroimagej"
cd /usr/local/bin
tar xvzf
AstroImageJ_Script.tar.gz
Following the usual
Linux convention, only lower case letters are used for the command line
scripts. You may prefer to name it
"aij" if you use the command line often, or
as root in /usr/local/bin provide a soft link:
ln -s astroimagej aij
For Linux or other Unix installations note the recommended X11 resource change
below.
Additional note about
64-bit Linux and 32-bit Linux
====================================================
AstroImageJ will run
with either the Sun or OpenJDK version 6 or higher of
Java. For OpenSuse we find that the 13.1 default OS
installation with OpenJDK 7 works fine.
Installing to older
Linux systems with a 2.6 series kernel may fail for
large memory machines, especially if they have had
a long uptime. In that case, if installing
an up-to-date distribution is not an option, we recommend running AstroImageJ
with the 32-bit JRE that is included in the ImageJ 32-bit package distributed
by NIH.
Copy the 32-bit jre subdirectory from ImageJ to AstroImageJ and modify the astroimagej script in /usr/local/bin/
to
#!/bin/sh
cd /usr/local/AstroImageJ/
./jre/bin/java -Xmx3072m -jar ij.jar
exit
The memory limitation
with 32-bit java is less than 4 GB, and about 3 GB as shown is the maximum
practical limit. With 64-bit java, the limit
is
approximately 12 GB.
X11 Note:
=========
The KDE and Gnome
window managers for recent distributions of Linux allow the user to control the
double click timeout. However, they do
not convey this to X11, so Java applications and many other programs that rely
on X may default to a 200 millisecond timeout that is apparently too
short. The solution is to add the
following line to either /etc/X11/Xresources (the
system wide default in OpenSuse) or on a user basis
to .Xresources in each user's home directory:
!
===========================================================================
! Local
Modifications
!
===========================================================================
*multiClickTime:
500
The change will take
effect after X is started the next time.
