TESTING SPIDER

Some simple tests are available to see if SPIDER is operating correctly. If SPIDER does not run:

• If you get an error message like: command not found

  See "Setting 'spider' command" above to ensure that your desired executable is accessible.

• If you get a error message about a missing library:

  The executables distributed with SPIDER are mostly statically linked so this should not be a problem. Any missing libraries are probably system libraries (unless you are trying to use the MPI version of SPIDER). You can use: ldd your-spider-executable to investigate missing libraries.




• If SPIDER runs but complains about the 'Nextresults' script which increments the Results file version number

  Your Linux distribution (e.g. Ubuntu) may have a non-standard sort operation.

  Edit: spider/bin/Nextresults and replace:

  lastfi=`(\ls $1.[0-9]* | sort -t. +2n | tail -1)`

  with

  lastfi=`(\ls $1.[0-9]* | sort -t. -k2 -n | tail -1)`

• If SPIDER still does not run
