[gentoo-science] New category proposal - sci-vis

[gentoo-science] New category proposal - sci-vis

[Marcus D. Hanwell]

[-- Attachment #1: Type: text/plain, Size: 1050 bytes --]

Hi,

I would like to propose the addition of a new category - sci-vis. The category 
is intended for scientific visualisation tools. Many of these are currently 
in media-gfx and I don't think they belong with photo editors, image 
conversion tools etc. The category is quite big already and most of the 
ebuilds in there are maintained by quite different herds.

Looking through the tree these are the apps I think should be moved to 
sci-vis:

media-gfx/epix 
media-gfx/fig2sxd 
media-gfx/gnuplot 
media-gfx/grace 
media-gfx/kpl 
media-gfx/labplot 
media-gfx/opendx 
media-gfx/opendx-samples 
media-gfx/qmatplot 
media-gfx/quickplot 
media-gfx/scigraphica 
media-gfx/spectromatic 
media-gfx/xd3d 
media-gfx/xgraph 
sci-misc/gwyddion 
sci-mathematics/qtiplot

There could be others I have missed, and there are certainly more that I can 
see in bugzilla that will be added. I would appreciate feedback on this. If 
everyone is in agreement then I will make this proposal on the gentoo-dev 
list.

Thanks,

Marcus

+1 for me. There are also visualisation applications in other categories, such 
as matplotlib in dev-python, but I suppose we should only move end-user 
applications to sci-vis, not ploting libraries such as matplotlib and plplot.

Hi,

I've been looking for a vector field visualizating program for quite
some time know. Do you know one?

There may be others, but I can't think of them at the moment.

Hi Marcus.

Thanks for picking this up!
I did not realise we did not have kpl, gun/labplot and others under some sci 
category yet, so I think this would be nice to do indeed.
Just one suggestion:
all the sci-* categories are in fact full words and not shorthands, so it 
would make sense to make this a full word too. Something like 
sci-visualization or sci-plot.

Oh, another one. When you submit the proposal to -dev it will be nice to 
include an estimate of how many other plotting/graphing packages we have 
lined up in bugzilla. Not that it makes it any stronger with the list of 16 
already in portage :), but still is nice to have..

Yeah - I have to admit I favour the shorter category names personally. If we 
are going to use a long one then I think it should be sci-visualisation (or I 
guess the American spelling sci-visualization) to keep it more general. There 
any quite a few apps that deal with visualisation such as gwyddion and some 
of the molecule rendering packages. It was intended mainly for the plotting 
packages that are mostly in media-gfx right now.

I wasn't so sure on the long versus short, but if that is a policy we have as 
a herd I will stick to it.

There are quite a few possibles - I was going to look at drawing up a list of 
some of them. I am sure I won't catch them all though.

It stands for much of the tree outside sci as well (app-mobilephone,
app-emulation, app-accessibility, games-simulation et al.). After much
discussion in the past, probably on -dev, it's just as easy for somebody
to tab-complete one or the other. But one name makes instant sense to
anyone looking at it, and the other requires some thought to figure out.

Thanks,
Donnie

+1 from me! This will make it much easier to track
things down.

Depending on the "definition" of visualisation and hence sci-vis
this category could also include

sci-chemistry/pymol

and possibly 

sci-chemistry/molden

since both visualize molecules. Particularly pymol doesn't
seem to really fit in sci-chemistry since it is geared toward
biomolecules and could as well be in sci-biology. The same
will hold for vmd once I am done with the ebuild.

cheers,
Markus

I was hoping to keep it as wide as possible so as to include things like that. 
For example gwyddion is an SPM visualisation app. That is why I was going 
with vis rather than plot or graph etc. So I would be in favour of adding 
them to the list.

Macromolecular graphics tools I really consider biochemistry, so they
can go either way. But I more often hear biochemistry elongated as
biological chemistry than chemical biology. So if forced to categorize
one or the other, I lean toward chemistry.

It all depends on the size of the molecules and the amount of 
specialization of the researchers, I think. We could go to the extreme 
of a category for each package if we were perverse enough. :)

I'm just starting to explore the Bioconductor Project 
(http://www.bioconductor.org). When all is said and done, Bioconductor, 
though it's primarly a collection of R code for cancer and genetics 
research, is really applied math and computer science. For example, I'm 
using some of the routines in Bioconductor for computer performance 
engineering.

Of course, my father was a biochemist and the correspondences between 
computer science, computational biochemistry and genetics were not lost 
on me. In short, my vote is for biology or biocomputing or 
bioinformatics rather than biochemistry or chemistry.

Just on the off chance some of you are interested in the heavy stuff, 
the good folks in Seattle at the Fred Hutchinson Cancer Research Center 
are having an advanced R programming class in January. I've already 
spoken to the organizers and they've assured me that the course is more 
about R than bioinformatics and that computer scientists like myself are 
welcome. If I go I will be bringing a Gentoo laptop, of course. :) For 
more details, visit  https://cobra.fhcrc.org/rforbioc/

Hi Donnie,

That sounds absolutely fine! Personally, I find it often
difficult to assign life science related tools to specific
categories. The boundaries between biology, chemistry,
biochemistry, or physics in the life sciences have become
fairly blury to me.

My point was mainly to say that once a sci-visualisation
category exists, users might expect to find tools like
pymol, vmd, etc. in there as opposed to sci-chemistry or 
sci-biology.

best,
Markus

Certainly sounds reasonable. I just found myself forced to justify the
current category. =)

Just to confirm that I have added the new category and moved all the 
applications that were in my list. Please let me know if there are any that I 
have missed. Also let me know if you spot any issues with the move that I 
might have missed. I went with the longer name as that was the prevailing 
opinion (still preferred the short name myself).

The category is intended for visualisation applications, so please don't move 
any libraries such as plplot etc into there. I know there are also some very 
hazy applications such as gmt which is now very generic and used by many more 
people than just geo-sci folks. So I welcome discussion on anything else you 
might feel should be moved. It is good having them out of media-gfx though :)

Now the question is, can we put less general-purpose visualization
programs there? For example, molecular graphics programs.

I personally would say yes, and that is why I wanted to keep it general. 
However I can see the argument for them going in sci-chemistry too. I was 
tempted to put stuff like easychem in there as it has no real purpose other 
than to draw chemical structures for print etc. I welcome the opinions of 
others on this.

I'd leave chemistry programs in the chemistry category. Same with 
biology, astronomy and mathematics. The new category fits well for 
things like graphviz and opendx.

By the way, I don't know if I mentioned this but I took a course in 
Advanced R Programming the week before last. I am toying with the idea 
of trying to put together an ebuild schema/eclass for R packages, 
similar to what Dirk Eddelbuettel has done with Quantian for the Debian 
distro. Who's the current R guru amongst the developers? I can share 
notes if you're interested.

I would tend to say yes, since molecular graphics programs can vizualize
everything from small molecules to large biomolecular systems.
Hence, I would have a hard time deciding if, e.g. VMD should
be sci-biology or sci-chemistry, whereas sci-visualization seems
natural. I would really like to hear opinions before I commit
VMD to portage. 

Thanks,
Markus

Apparently it's more than a "proposal" ... tonight's "emerge --sync" 
moved some packages, breaking some ebuilds in the process. I haven't dug 
into it enough to file a bug yet, though.

Top posting does break the flow of conversation, but I already said a fair few 
posts up that I had completed the initial move of 17 packages to the new 
sci-visualization category after asking for commend here months ago, and 
comment on -dev weeks ago.

No further packages have been moved that I can see, and the only small 
breakage was the opendx-samples dep on opendx. I have manually scanned 
through the tree for any other broken deps and cannot find any.

That is my general feeling, and these packages tend to be used by a large 
cross section of the scientific community. At the end of the day better 
metadata and search facilities would help as many packages belong in multiple 
categories. For example qtiplot has a large array of mathematical fitting 
routines and so did kind of belong in sci-mathematics too, but primarily it 
is about visualisation of data. Stuff like gwyddion (SPM analysis) doesn't 
fit anywhere else easily.

My maxima 5.9.2 ebuild from the sci overlay is looking for gnuplot in 
the old category. Don't know if the older maxima ebuilds have the same 
problem; I run bleeding edge science software on most of my machines.

Personally, I would rather keep the specialised visualisation applications in 
their respective categories and use sci-visualisation for general-purpose 
tools. Doing otherwise would create confusion, I think. For instance, should 
TreeViewX be moved to sci-visualisation? After all, it is a visualisation 
program for phylogenies produced by other tools, such as PHYLIP. However, 
users are more likely to search for that tool in sci-biology. Does a genome 
browser belong in sci-visualisation? What about packages such as EMBOSS, that 
propose a few visualisation programs, along with analysis tools?

I think it is better to classify packages according to their field of 
application, and keep visualisation packages that are not tied to a 
particular field in sci-visualisation (ie. statu quo).

After thinking about this some more I have to agree with
Oliviers point of view.

Why is that? I think that sci-vis would be a perfect place for,
for example, VTK.

It is because you cannot fire up a lib and run it to do something, other 
programs use it to do something like visualisation. Therefore sci-libs would 
be a much more appropriate place as it is a scientific library - to be useful 
somebody needs to build an application that uses it. Again this is my opinion 
and I welcome discussion on the matter. I don't see any reason to start 
placing libs in there though, or any of the other sci-* categories.
