Manual for the Staden Package
|
||
|
|
-----------------------------
|
||
|
|
|
||
|
|
There is now a 135 page manual on the Staden Package. It is currently
|
||
|
|
being distributed on a Word4 document on a Macintosh floppy disk.
|
||
|
|
|
||
|
|
|
||
|
|
Feedback and bug reports
|
||
|
|
------------------------
|
||
|
|
|
||
|
|
We welcome comments and suggestions on all aspects of the package and are
|
||
|
|
best contacted by email: rs@uk.ac.cam.mrc-lmb and sd@uk.ac.cam.mrc-lmb.
|
||
|
|
All abnormal terminations are bugs and we would like to be told of them
|
||
|
|
so they can be fixed. We recommend that you request an update at least once
|
||
|
|
a year as the package is evolving very rapidly.
|
||
|
|
|
||
|
|
Note due to popular demand we have decided to release new routines earlier
|
||
|
|
than in the past so please report bugs. The documentation for additions may
|
||
|
|
be sparser than before, or non-existent, but if there is something with which
|
||
|
|
you need help, email us.

Changes this release
|
||
|
|
--------------------
|
||
|
|
|
||
|
|
|
||
|
|
The assembly programs bap and xbap heve several new functions:
|
||
|
|
1. Find single stranded regions and try to fill them with "hidden"
|
||
|
|
data from the adjacent readings.
|
||
|
|
2. Find single stranded regions (includes ends of contigs) and
|
||
|
|
select primers and templates for double stranding them (joining
|
||
|
|
them).
|
||
|
|
3. Pre assembly screening for readings to find those that align
|
||
|
|
best. Optionally the hidden data can also be included in the
|
||
|
|
comparison (part of assembly function).
|
||
|
|
4. Find pairs of readings taken from opposite ends of the same
|
||
|
|
template (ie forward and reverse read pairs). List or plot their
|
||
|
|
positions.
|
||
|
|
5. A new function to check that readings have been assembled into
|
||
|
|
the correct positions. It aligns the hidden (previously termed "unused")
|
||
|
|
parts of readings with the consensus they overlap to see how well
|
||
|
|
they align. Poor alignments are reported.
|
||
|
|
6. During assembly each reading is now allowed to match up to 100
|
||
|
|
different places.
|
||
|
|
|
||
|
|
It might be guessed from the above that we are trying to improve our
|
||
|
|
ability to deal with the assembly of human data. Hence, also the next
|
||
|
|
addition.
|
||
|
|
|
||
|
|
A new experimental program (rep) for screening readings for Alu
|
||
|
|
sequences prior to assembly. The Alu containing segments are tagged
|
||
|
|
so they can be seen in the contig editor. A library of Alu sequences
|
||
|
|
is included in /tables/alus. The program is quite slow as it compares
|
||
|
|
each reading in both orientations with all of the Alu sequences (126
|
||
|
|
of them) in order to find the best match. Only time and more data will
|
||
|
|
tell how sensitive it is, and whether the current default score 0f 0.6
|
||
|
|
is "correct". BEWARE rep modifies the original reading files to include
|
||
|
|
the tag information. The only information is in /help/alu.help
|
||
|
|
|
||
|
|
A new program for extracting sets of sequences and their annotations
|
||
|
|
from the sequence libraries (lip). The only information is in
|
||
|
|
/help/lip.help
|
||
|
|
|
||
|
|
Changes to the xterm userinterface. These routines have been completely
|
||
|
|
rewritten. One addition is that now ?? in response to a question will
|
||
|
|
allow the user to get help on any function in a program. help is also
|
||
|
|
improved in the x version.
|
||
|
|
|
||
|
|
|

|
|
Changes last release
|
||
|
|
--------------------
|
||
|
|
|
||
|
|
|
||
|
|
DAP, XDAP have been replaced by BAP and XBAP (see below)
|
||
|
|
|
||
|
|
A new function for examining repeats has been added to NIP
|
||
|
|
|
||
|
|
A new repeat search has been added to SIP
|
||
|
|
|
||
|
|
Some outputs have been changed to produce FASTA format files
|
||
|
|
instead of PIR.
|
||
|
|
|
||
|
|
MEP now allows searches for motifs in which any 8 out of a string
|
||
|
|
of 20 can be switched on.
|
||
|
|
|
||
|
|
The manual has been updated.
|
||
|
|
|
||
|
|
Keyword and author searches on sequence libraries
|
||
|
|
|
||
|
|
All programs that use the libraries can now perform author
|
||
|
|
and keyword searches on all libraries (only nip did so before).
|
||
|
|
|
||
|
|
Postscript output
|
||
|
|
|
||
|
|
All graphics can now be saved to disk in postscript form by
|
||
|
|
use of a sub-option in "Redirect output".
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
Sequence assembly
|
||
|
|
|
||
|
|
BAP, XBAP replace DAP and XDAP. A program to convert DAP databases to BAP
|
||
|
|
databases (convert) is included. BAP databases can contain up to 8000 readings
|
||
|
|
and a consensus of 500,000 bases. A minor edit and recompilation will allow
|
||
|
|
up to 99,999 readings. The space is used more efficiently now as the databases
|
||
|
|
grow as the number of readings increases. Reading names can be 16 characters
|
||
|
|
in length. In addition:
|
||
|
|
|
||
|
|
1) Assembly is 4 times as fast as in the DAP.
|
||
|
|
|
||
|
|
2) Find internal joins is 5 times as fast and now brings up the join editor
|
||
|
|
with the two contigs in the correct orientation and aligned.
|
||
|
|
|
||
|
|
3) The assembly routines align pads better, plus a new automatic function can
|
||
|
|
also be used to align them prior to editing.
|
||
|
|
|
||
|
|
4) The contig editor has been greatly speeded up and its functionality
|
||
|
|
has been enhanced.
|
||
|
|
|
||
|
|
5) A routine for selecting oligos for primer walking is included.
|
||
|
|
|
||
|
|
6) A new routine allows batches of readings to be removed from a database.
|
||
|
|
|
||
|
|
7) We have also included routines for making SCF files, for getting the
|
||
|
|
sequence from SCF files, and one for marking the poor quality data in
|
||
|
|
readings. See the manual.
|
||
|
|
|
||
|
|
Sequence library formats
|
||
|
|
|
||
|
|
The standard sequence library indexing method is now that used on the
|
||
|
|
EMBL CD-ROM. The libraries (EMBL nucleotide and SWISSPROT protein) can be
|
||
|
|
left on the CD-ROM or copied to disk. We include in the package programs
|
||
|
|
for creating this type of index for EMBL updates, PIR in codata format,
|
||
|
|
NRL3D and GenBank. If the indexes are created all programs can read all
|
||
|
|
these libraries. Programs and scripts for this task are contained in the
|
||
|
|
directory indexseqlibs.
|
||
|
|
The keyword and author searches are particularly fast and the
|
||
|
|
keyword index is based on ALL text in the files - not just the keywords.
|
||
|
|
|
||
|
|
Feature table formats
|
||
|
|
|
||
|
|
The programs now use the new feature table format common to EMBL
|
||
|
|
and GenBank, but retain the old format for SWISSPROT which has not yet
|
||
|
|
changed.
|
||
|
|
|
||
|
|
For details of the above see file SequenceLibraries.
|
||
|
|
|
||
|
|
Pattern searches
|
||
|
|
|
||
|
|
Pipl and Nipl now have the facility to find only the best scoring
|
||
|
|
match for each sequence. The prompt is "? report all matches", so typing
|
||
|
|
only return means all matches will be shown and typing n means only the
|
||
|
|
highest scoring will be reported. It is particularly useful when employed
|
||
|
|
to create alignments. The corresponding help file has not been updated.
|
||
|
|
Also to incorporate long unix file names the pattern files no longer include
|
||
|
|
the annotation "filename".
|
||
|
|
|
||
|
|
|
||
|
|
Nip
|
||
|
|
|
||
|
|
Option 38 in nip "translate and list" has been removed as the the
|
||
|
|
more flexible routines of option 39 incorporate all its functionality. Many
|
||
|
|
options that relate to feature tables have been modified but their help files
|
||
|
|
are not yet up to date.
|
||
|
|
|
||
|
|
|
||
|
|
Vep
|
||
|
|
|
||
|
|
A program (vep) for automatic excising of vector (either
|
||
|
|
sequencing vector or cosmid vector) sequences from readings is now
|
||
|
|
included in the package.
