- Added question at end to ask if print out wanted now.
- 7/6/92 AL
- CS DI PO
- Added a menu driven interface
- 7/24/92 AL
- PF
- Asks if immediate postscript plot wanted
- 7/24/92 AL
- Pl
- Asks if immediate postscript plot wanted
- 7/24/92 AL
- CO
- Takes multiple input files, accesses postscript menu
- 7/24/92 AL
- TV WK

- 8/15/92 AL
- CA SME
- Doc. file option no longer asks for column, bugs fixed
- 9/14/92
- AL
- CA CLAF
- Decreased array limits to old values to avoid bug
introduced by increase of limits in Aug 91.
- 10/20/92
- AL
- WT TV
- Interactive lattice picking is done using WEB to make
a doc. file then 'WT TV' to do the lattice refinement.
- 10/30/92
- AL
- X0 use
- X0 now works properly in filenames
- 12/31/92 AL
- --
- Interactive access to manual chapters possible
at all prompts using a ? response.
- 05/05/92 ML
FS
Order of optional registers changed.
FS XM,XN,XO,XP
XM = maximum (was minimum)
XN = minimum (was maximum)
XO,XP unchanged
This change may affect existing procedures. Check
them for usage of FS!
1/23/91 MR
MR
The program has been corrected such that mirror at
x-axis really interchanges the lines of the image
and mirror at Y-axis interchanges the points in the
line. Before the program wrongly did the oposite.
If 'MR' is used in procedures they need to be changed.
3/15/91 MR
MO 3
Operation 'MO 3', option C (cylinder) now asks extra
questions. (volume background and cylinder axis)
s. manual.
8/9/91 MR
RT 3
Sign of beta changed. It now is consistent with the
sign in 'BP XY' and other 3D programs.
10/22/91 MR
--
The global error flag (register 99) is no longer
supported.
10/24/91 > AL
AS
The 'add series' commands (AS, AS R, AS AD, AS DC)
were modified. One question was added:
All/Odd/Even ? It allows the use to average
either all images from the given series, or only
each second (odd- or even-numbered). This provides
easy way to create two subaverages to check the
resolution or compare them in some other way.
10/24/91
OR 3Q
Command 'OR 3Q' was added. It helps to determine the
orientation of two volumes in terms of three
Eulerian angles.
10/25/91
CP TO VAX
Command added for conversion of Unix SPIDER or
Unix 8 bit raw raster images to VAX SPIDER images.
11/8/91 AL
- INTEGER*4
- INTEGER*4 arithmetic is now used throughout. The INTEGER*2
arithmetic was a leftover from the time when memory space had to
be conserved in the original PDP-11 implementation of the system.
- Summer 1987 AL
- Single-task version.
- Introduction of a single-task version has entirely eliminated
the problems of inter-task communication, including delays and
locked files.
- Summer 1987 AL
- DOCUMENT files key length increased.
- The maximum number of keys in DOCUMENT files has been increased
to 9999. This increase has been necessary because of problems
that require an image or projection pool with more than 999
images.
- Summer 1987 AL
- In-core retrieval of registers from DOCUMENT files.
- Retrieval of registers from a document file by repeated sequential
access in a SPIDER DO-LOOP is very inefficient. Therefore an
in-core unsaving option (UD IC) has been created which allows up to
two document files with up to six registers each to be stored
in memory for the duration of the SPIDER session.
- Summer 1987 JF
- Symbolic parameters in procedures
- Previously only 9 ould be used. This number has now been
extended to 99.
- Summer 1987
- Long procedure names.
- Procedure names can now be up to eight characters long; e.g.
align45, corav.
- Summer 1987
- On-line computation of input arguments in operations.
- At the place where a number or a pair of numbers is solicited,
an arithmetic expression, or a pair of expressions, involving
registers may be used.
- Summer 1987
- Arguments in procedures.
- It is now possible to pass arguments in registers to/from a
procedure. This feature emulates subroutine calls in FORTRAN.
- Spring 1989
- Long file names.
- File names can be up to 80 characters in length, and can contain
references to directories.
- Spring 1989 AL
