ISDAT is a database for accessing satellite data, in particular Cluster and Cassini. This page is part of an attemp to create an easy to install distrtibution of ISDAT clients. The distribution includes the following clients:
UNIX like environment is needed. The following platforms were tested: FreeBSD(i386 and amd64), Linux (amd64), MacOSX, Solaris, Cygwin*.
*see special notes on Cygwin.
Here is a current (January 2011) distribution: isdat-clients-2.9.0.tar.gz
*see also special notes on Cygwin.
Unpack the distribution
> gunzip isdat-clients-2.9.0.tar.gz > tar xvf isdat-clients-2.9.0.tar > cd isdat-clients-2.9.0
Compile and install
> ./configure --prefix=/usr/local/isdat --with-matlab=/opt/matlab > make > make install
This will give you iscmd and ctm installed under /usr/local/isdat/bin. You can optionally create links under /usr/local/bin:
> cd /usr/local/bin > ln -s /usr/local/isdat/bin/iscmd . > ln -s /usr/local/isdat/bin/ctm .
> iscmd
iscmd: Usage: iscmd p|q|c|d|i [isdat_URL] [start_time] [duration] [tm]
isdat_URL := isdat://host.domain:port_no/logical_instr
start_time := yyyy-mm-dd hh:mm:ss.ns
p : (ping) check if server is alive
q : (query) list constituents of logical_instr
c : (contents) list intervals of available data
d : (data) get logical_instr data from start_time for duration
i : (indexgen) generate index files for logical_instr
tm: Returns TM data and not the default calibrated data

All questions regardin installation/compilation should be e.mailed together with a config.log file to yuri NOSPAMAT irfu DOT se. All other bugs must be submitted via ISDAT Bug Reporting Page.
Cygwin allows you to have a UNIX-like environment on Windows. You need to install Cygwin on your PC (including X) before you proceed with installation of ISDAT clients. Here is a list of additional packages needed:
bison (Devel: bison) flex (Devel: flex) gcc (Devel: gcc) libtool (Devel: libtool) make (Devel: make) file (Utils: file) lesstif (X11: lesstif) X headers (X11: xorg-x11-devel)
After this you can follow the usual installation and running instructions.
NOTE: (1) X must be running (type startxwin.sh in the Cygwin prompt) to run ctm/igr; (2) Matlab client does not and will never work on Cygwin.
