WHATS NEW IN SPIDER (BEFORE 1993)

Important changes made before 1993 are listed here.

       1992     1991     1989


1992

RT 90
Rotates image or volume by 90,180, or 270 degrees by reslicing the object. (center not same as 'RT')
1/20/92 AL
MR
Works for 3D files.
PP
CC C
Works for 2D and 3D data.
PP
FT MR
FFT for non-power-of-two dimensions
PP
CC MR
CCF for non-power-of-two dimensions
PP
PW
PW for non-power-of-two dimensions
PP
PW L
PW L for non-power-of-two dimensions
PP
AP ...
Alignment programs work for non-power-of-two dimensions
PP
SH F
Removed
PP
SH 3
New 3D shift. Uses correct interpolation and is fast.
PP
RT 3D
The values in the corners are left unmodified.
PP
PJ 3Q
New 3D projection command. Calculates the series of projections according to the angles stored in the document file.
PP
PJ 2COL
New program for combination of two objects in two colours.
5/28/92 MR
CP TO POST
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
Interactive particle selection Works on Decwindows now
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

1991

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

1989

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
