+ZMap/Otterlace Development
+
+
+Date:  Thursday 12th Feb 2009
+
+Attendees: jgrg, jla1, lw2, edgrif, st3, br2
+
+
+------------------------------------------------------------------------------
+CURRENT ITEMS
+
+
+Items Completed
+---------------
+
+automating DE line creation
+
+adding all checks fropm kj2's script to lace
+
+3/ Data for zebra fish DAS tracks needs mapping between assemblies is done.
+
+
+
+
+High priority
+-------------
+
+1/ Tick boxed for controlled vocabulary
+
+***** jla1 wants this to be top, top priority *****
+
+jla1 said there is an urgent need to add "tick boxes" to the lace interface to
+ensure that certain properties of annotated features can only be chosen from
+a controlled vocabulary. lw2 to check whether "fragmented_loci" is included
+in the tags. lw2 said all other tags are in the RT ticket: NNNNNNNNN
+
+1a/ Locus Finished button
+
+st3 asked if there could be a tag on a Locus to say it was Finished,
+implemented via a button so that the correct tag(s) were automatically
+entered. jgrg to implement.
+
+1b/ Clone Finished button
+
+st3 would like a "Clone finished" button with same function as Locus Finished
+button. jgrg to implement.
+
+
+2/ Clone summary info / Quality Control
+
+jgrg has done lots of work on this and summarised his progress in an
+email circulated to us all.
+
+Following on jla1 also suggested that it would be good to have
+automated QC scripts trawling through the database regularly looking for
+duff data. Tina Eyre wrote one that could be co-opted and st3 also has
+some. This is becoming an important issue for Havana to ensure really
+good quality data. Add automated checking against SwissProt for CDS.
+
+jgrg said that much of the checking was done for annotation and he will circulate
+an email summarising this. QC for save to data back to Otterlace need doing though.
+
+We need an "end_missing" tag as well as the current "end_not_found" tag.
+
+
+3/ SNP tracks
+
+jla1 would like some of the DAS tracks & other data sources currently available
+to be put into lace and hence zmap. jgrg said that this is not immediately
+straight forward as they don't all say which assembly they are based on but some
+can be done fairly soon. e.g. comparacon ? jgrg to investigate.
+
+
+4/ Styles
+
+James working to introduce this now, zmap code is all there. jgrg is to set a week
+when he can work on this and edgrif will set aside the week also.
+
+edgrif needs to do 4 weeks approx of acedb work in two 2 weeks lots so suggests 
+we set week beginning 16th March as the week to do styles (i.e. the week after
+the RT course).
+
+
+5/ Solexa reads
+
+jla1 would like to get Solexa reads into pipeline including data from Bronwyn.
+
+As an addition to this edgrif and rds will think about how we might give some
+kind of "overview" for alignment columns that could show where the aligns are
+without drawing them all.
+
+Also requires looking at blixem to see if we can view this data in it.
+
+In fact John Collins has initial data for gene models and confirmed introns
+that can be added now without code changes. This data is coming from Simon
+Whitehead.
+
+James will indicate in display where sequence is missing.
+
+
+6/ Alias/renaming of Loci
+
+lw2 to contact MGI as there are problems with IDs from them.
+
+
+7/ clone path
+
+lw2 would like the full clone extents displayed with the non-golden sections displayed.
+Do we need the clone ends information for this, edgrif to check ?? Check with Leo's
+smapped example with several sections of a single clone...
+
+Would like this info. in navigator panel + navigator panel needs to display both
+the foocanvas scrolled window area _and_ the actual area on the screen, and both
+should be draggable...
+
+edgrif will do tile path information/display, rds will do navigator bit.
+
+
+8/ multi-view interactions
+
+kj2 would like to click on a feature in one view and see it highlighted in another
+so that she can look for genes present in more than one clone. edgrif to do this.
+
+
+9/ RT numbers
+
+It was agreed that where possible RT ticket numbers would be included in the
+meetings notes. lw2, edgrif, jgrg to look up numbers.
+
+NEEDS DOING.....
+
+
+10/ feature grouping tags (e.g. for 5'and 3' EST read pairs)
+
+wormdb uses paired tags specific to EST read pairs but we need a more flexible
+generalisation of this to handle multiple features and different types of
+feature. jgrg's group have been working on filtering hits in a better way and
+so have more information about grouping for display.
+
+Ed, James, Graham and Roy met to discuss design and edgrif has implemented
+code in zmap to support this but adding it to the system will require a
+time when both he and James can work on it.
+
+
+11/ Naming of Alternative Alleles
+
+-st3 asked about naming of alternative alleles in different mouse strains / human
+haplotypes. For loci that don't have HGNC/MGI names, these are incorrectly named after
+the clones on the reference seqiuence.  jla1 suggested correctly naming them after the
+clones they are on, but making sure that the annotators can see the associated
+'reference assembly' gene. st3 said this could be done via the alt_allele table, and
+if it were done across the board, ie including KNOWN genes, then this would make Vega
+prep easier
+
+
+
+
+
+
+Medium priority
+---------------
+
+0/ new column bump to show inconsistent matches
+
+Often annotator has many matches that fit against an existing transcript, be good
+to have a mode that hid these and only showed the ones inconsistent with the
+transcripts splices.
+
+
+1/ dotter error messages
+
+lw2 said that sometimes dotter just does not appear. edgrif to check that dotter
+is reporting errors properly and to make sure they show in dialog windows not on
+the terminal which is often not available to the annotator.
+
+
+2/ removing evidence already used *************
+
+annotators would like to be able to remove from display homologies that
+have already been used to annotate variants etc. Does this need to be
+persistent in the database in some way ?? edgrif & jgrg will get
+together to arrange this via styles so it can persist in a natural way
+in the database.
+
+**24526: Showing which evidence has been used
+Differential coloring of matches that have been used already as evidence
+for a transcript
+
+mainly requires jgrg to mark features and then tell zmap to move the features
+to a new column or repaint them with a new style.
+
+
+3/ Locus list
+
+jgrg to provide a list of loci as another tab window. + searching on ensembl ids.
+
+
+
+
+5/ bug in acedb server
+
+jgrg raised a bug in the server which was causing it run out of memory, edgrif
+to investigate. There is a ticket for this: 51894
+
+edgrif to make jgrg has up to date binaries for dotter etc.
+
+
+6/ popups/labels for transcripts
+
+jla1 said that apollo had a neat way of showing a label for a transcript
+that remained in one place on the screen as the window was scrolled. edgrif
+to investigate + look at "tool tips" for transcripts....especially with
+locus information. 
+
+
+7/ Best in Genome matches
+
+jla1 also said she would like to "best in genome" displayed. jgrg said this
+is not easy as Otterlace works on a clone by clone basis. It was agreed
+that would be worthwhile to show at least "best in clone" or better to do
+a crude "best in genome".
+
+
+
+
+------------------------------------------------------------------------------
+BACK-BURNER ITEMS
+
+
+
+ZMap/acedb
+----------
+
+1/ Interface issues:
+
+
+jla1 and lw2 said they would like the marked area to be less obvious an also to
+be a "greying" out rather than blue and with less dense dots. edgrif to implement.
+
+
+jla1 said she would like to be able to click on an exon and see evidence (and
+transcripts ?) with the same splice be highlighted. laurens also wants this
+as it would often avoid having to open dotter to check.
+
+
+
+2/ Display of multiple compara alignments
+
+multiple alignments: edgrif is about a third of the way through implementing a
+more general way of displaying arbitrary blocks.  This will become a high
+priority item as we move to haplotypes etc.
+
+th said this would be needed soon so it should be moved up the priority list.
+jgrg said they have mappings in lace that could be passed on to zmap easily
+and also said that annotators can already annotate assemblies from variants
+and different species alongside each other as needed.
+
+We need to decide on the format for specifying the alignments.
+
+
+
+3/ alternative translations: edgrif about half way through code to do this.
+
+edgrif is doing this as part of the protein search code since this code
+does translations itself. edgrif will talk to jgrg about how alternative
+genetic codes can be specified with acedb.
+
+We need a test database for this. jgrg said this would come soon.
+
+edgrif will add field to transcript feature to hold alternative translation
+table.
+
+
+4/ Blixem enhancements
+
+two areas:
+
+- display multiple overlapping transcripts better (includes removing the many
+yellow lines introduced by this...clarify this point), have a scrolled window
+of the transcripts. jgrg said that perhaps only the transcripts made by havana
+should be displayed. jla1 said she would like to be able to dynamically update
+the transcripts displayed.
+
+- better interaction with zmap, e.g. click on things in zmap and see them 
+highlighted in blixem and vice versa....
+
+we had better have a more generalised protocol for communicating with external
+programs....
+
+- blixem: dna searching is NOT DONE, edgrif to expedite. Also protein searches
+will be added.
+
+Perhaps one way to get this done would be employ a good C programmer on a
+short contract.
+
+
+5/ acedb server performance
+
+edgrif investigating two possibilities for improving performance:
+
+	- make sgifaceserver stream data rather than batch it up, would
+	  save a lot of memory.
+
+	- deferred loading, only load features when needed and load in
+	  zone requested by user....design done...now need to implement.
+
+
+6/ A new canvas
+
+rds has been looking at alternative canvas implementations which offer an MVC
+model. He has managed to get goocanvas developers to fix some bugs and make
+some changes to support our needs.
+
+the goocanvas MVC model will mean we do not have to copy data to split windows
+meaning greatly reduced memory usage.
+
+the goocanvas will cope automatically with the X Windows window size limit, this
+combined with changes in the gtk scrolling model means we will be able to do away
+with having two scroll bars.
+
+We will introduce the new canvas this year.
+
+
+
+
+Otterlace
+---------
+
+1/ Alternative alignment programs
+
+There has been some discussion about using splice aware alignment programs.
+jgrg is waiting for a fix to exonerate to support the new pipeline mustapha
+has written.
+
+edgrif and jgrg both commented that some changes to acedb data structures
+would be needed to represent both HSP's that are "joined up" but also 
+protein matches that start part of the way through a peptide. BUT one
+possibility would be for zmap to access this data directly from a mysql
+database thus sidestepping the need to put it in acedb first. gffv3 will also
+be needed to represent this kind of joined up HSP data in a natural and
+robust way.
+
+Changes will also be required to represent codons that are spliced across
+introns as perhaps surprisingly none of the acedb programs can cope with
+this currently (and neither can zmap).
+
+
+2/ Spell checker
+
+jla1 reported a problem that free text fields and some fixed text fields
+have misspellings (is that a mis-spelling ?) and it would be good to have
+some autocorrection facility. The ideal would be to have some widget that
+allowed other dictionaries (e.g. science) to be attached to it and could thus
+be used as a general text entry tool.
+
+
+
+3/ Sequence exceptions
+
+kj2 raised the subject of how to indicate sequence exceptions,
+e.g. when bases are skipped in translations. kj2 wondered if alternative
+translations could be registered as sequence exceptions, edgrif said he
+prefer a separate mechanism as much of the code is already done for this.
+We should therefore include a mechanism in zmap for sequence exceptions,
+this would require a similar mechanism in acedb. This is yet another reason
+for GFF 3 which has standards for frame shifts and other things.
+
+There should be a way of tagging transcripts where there are sequence
+exceptions.
