  SPIDER & WEB


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.
