SPIDER: Testing

TESTING SPIDER

• Start SPIDER

  cd SPIDER_DIR/bin
  spider
  .ENTER PROJECT/DATA CODE: PRJ/DAT
  .OPERATION:
  

• Test arithmetic operations.

• These are the "pocket calculator" functions which allow a wide range of arithmetic expressions to be computed. Expressions should be entered in the same way as FORTRAN arithmetic expressions appear in a FORTRAN source program.

  Enter the sequence:

  ((3-0.26)/4)**2.

• Test the use of registers and document files.

• Enter the sequence:

  [val]=2
  [cols]=5
  SD 1,[val],[cols]
  DOC001
  UD 1,[newval],[newcols]
  DOC001
  [newval]
  [newcols]
  

  The values 2 and 5 stored in the register variables [val] and [cols] should have been saved in DOC001.PRJ under the key 1 and subsequently retrieved into the register variables [newval] and [newcols]. Upon entering '[newval]', SPIDER should respond with '2.0000', and upon entering '[newcols]', it should respond with '5.0000'.

• Test file creation.

• Enter the sequence:

  MO
  JNK001
  16,16
  T
  FS
  JNK001
  

  The operation 'MO' creates a test pattern (a diagonal sine wave) image, and 'FS' gives some info about this image.

• Test a simple procedure.

• Enter the sequence:

  @M01
  

  'M01' refers to a procedure file M01.spi that is part of the SPIDER distribution, which contains the sequence previously entered in the interactive mode, with the addition of 'MD' with 'TR ON' added which causes all commands used within M01.PRJ to be shown on the terminal as they are executed and 'GR' added which causes a graph of line 12 in the output image to be printed in the RESULTS file. The RESULTS file: results.PRJ.0, can be printed on a line printer.
