The 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 or in Java and is used for visual display and interaction with images created by the SPIDER module or to be used by SPIDER.
Platforms: We regularly run SPIDER/Web on various platforms including: AMD Opterons running Linux, Intel Pentium Xeons running Linux, SGIs running Irix, and SGI Altix's running Linux. Our current preferred platform is a Dual-Core Dual-Opteron based machine running SUSE OS. Heavy computations are done in parallel on a cluster of these machines. SPIDER requires at least 128 Mb of memory.
On Linux, and other Unix machines: The SPIDER and Web modules contain precompiled executables for: AMD 32 and 64 bit platforms, Intel 32 bit platforms, and SGI Itanium platforms. The modules also contain all source code, and sample Makefiles for module generation on various GNU-Linux architectures and for IBM SP3 systems running AIX.
On SGI Irix: The modules contain executables for use on Irix 6.0+ The modules also contain all source code, and Makefiles needed for module generation.
On Other systems: We test SPIDER/Web on Irix and GNU-Linux. We no longer provide the Windows or Compaq (DEC) Unix versions.
Compilation and linking: It is possible that one of the SPIDER/Web executables which we supply will run on your machine. However the code may have to be recompiled and linked for use on some machines. Such compilation will require familiarity with the local operating system to set the necessary compilation/linking flags and libraries. Compilation of SPIDER requires a FORTRAN 90 compiler. We currently use a PGI compiler on Linux, SGI compilers for Altix and Irix, and IBM compilers for AIX. Compilation and linking of Xwindow WEB requires a C compiler and Motif/X-Window libraries on your computer. The standard gcc compiler works well. Please understand that we may not be able to assist with problems you encounter running SPIDER/Web on machines other than those listed above. You may be able to view SPIDER format images without installing Web.
