SYSTEM AVAILABILITY
The SPIDER distribution consists of two separate modules, SPIDER and
Web. The SPIDER module is written in FORTRAN and is used for
mathematical manipulation of images and their contents. The Web module
is written in C and is used for visual display and interaction
with images created by the SPIDER module or to be used by SPIDER.
SPIDER/Web requires an 8 bit color workstation with at least 32 Mb of
memory (64 Mb preferred). You should have at least 4 Gb of disk space
for your images. A 24 bit color workstation is NOT necessary but may be
useful if you wish to run programs other than SPIDER/Web for advanced
visualization of results.
Recompilation and linking of SPIDER requires a FORTRAN compiler while
recompilation and linking of WEB requires a C compiler and
Motif/X-Window libraries on your computer.
We now provide SPIDER/Web only for UNIX. The VAX/VMS version has
been discontinued. The software has been
developed and tested on SGI workstations. Some sites are running
it on DEC Unix workstations and one site has some experience on
SUN workstations, but at this time we still advise running it on SGI
systems.
DISTRIBUTION
On SGI: The UNIX SPIDER and Web modules contain executable versions of SPIDER for
use on SGI workstations running Irix 5.0+ and Irix 6.0+. The modules contain all
source code, object libraries, and makefiles needed for module
generation.
On DEC, Sun, and other Unix machines: The modules contain sample
Makefiles, object libraries, and executables for use on
DEC-OSF, and Sun Sparc-Stations. The modules were targeted at
SGI workstations and have not been extensively tested on non-SGI
workstations. It is probable that SPIDER/Web will work on non-SGI
Unix implementations, however, the FORTRAN and C code which we supply
may have to be recompiled and linked on those machines. Such
compilation will require familiarity with the local operating system
to set the necessary compilation/linking flags and libraries.
Please understand that due to limited staff and equipment we may
not be able to assist with problems you encounter porting SPIDER/Web
to non-SGI machines.
Media: CDROM, 4mm DAT DDS2 tapes, QIC 150 tapes, or ftp transfer
IMAGE DISPLAY WITHOUT WEB
It is possible to view images from SPIDER on most workstations
without using Web. You could write your own software to
do this using Web as a model. Alternatively you can use the
"CP TO RAW"
command in SPIDER to convert a SPIDER format image to a 8-bit "raw"
image. Most 8-bit color or black-and-white workstations (including
SUN) have a native graphics command for display of such images or
conversion of such images into their own format. If you choose to go
that route, you can deal with basic display functions but cannot
easily emulate many interactive functions such as interactive
windowing contained within Web.
