Another Wine problem ... Out of memory
- Login o registrati per inviare commenti
Been using Wine in Belanos for a couple of years ... namely with PSI-Plot,
a very stable Windows App which I have been using since it ran on DOS 6.22.
PAI-Plot is a spreadsheet program that is integrated with a mind-boggling
set of mathematical and graphical plotting applications on which I depend.
First clue:
After installing Flidas in dual-boot mode next to Belanos (different
partition, of course) I noticed that my usual sort of one column of data
in the raw access file for one month of my domain in LibreOffice Calc
running in Belanos stalls, but in LibreOffice Calc (5) in Flidas the same
sort is blindingly fast.
Second clue:
After sorting the raw access file and separating a tiny portion (150kB
out of 60MB) I found that I could upload the .XLS version of the saved
separate data from LibreOffice Calc into a PSI-Plot spreadsheet, but that
in one column some of the cells were empty and that in another column
most of the cells were empty. The dubious cells had contained mixes of
text characters and arabic numerals.
Third clue:
Thinking that the dual boot installation of trisquel_7/_8 might be the
cause of these errors, I restarted the laptop with the external 1.0TB
USB-connected hard drive running _only_ Flidas. Then I installed Wine
using apt-get and installed PSI-Plot with wine from the original
PSI-Plot CD disk, which went OK. But after opening the small separate
raw access data file in LibreOffice Calc (still version 5) and saving it
again as an .XLS file, when I tried to open that .XLS file in PSI-Plot,
I got an "out of memory" error right at the beginning of the conversion.
Fourth clue:
The laptop has plenty of memory: When I make panoramic images from as
many as two dozen megabyte digital images, Panorama runs great, using
all the memory, raising the temperature of the CPUs to about 90C, and
never crashes.
It would seem that memory management is the issue ... and it has come
to pass since I started upgrading the various hard drives to run Flidas.
The internal hard drive of the laptop has the dual boot Trisquel OS's,
but the external USB-connected hard drives are running just Flidas,
because that installation replacing existing Belanos installations
did an excellent job of managing all the various applications.
I don't mind if LibreOffice Calc has been irreversibly changed by
updates of the Belanos installation in the dual boot configuration,
but I'm surprised that the clean installation of Flidas in the single
boot external hard drive is not managing RAM.
Maybe I should reboot after using LibreOffice Calc to prepare the
.XLS version of the small separated raw access spreadsheet and see if
that releases some memory.

PSI-Plot is proprietary software. Apparently, you only face problem with that program. No free software program you could use instead? R is not easy to learn but there are simpler (although not as powerful) alternatives such as PSPP, SciDAVis, etc.
Observation: you only run one operating system. Having multiple distributions installed cannot be the problem.
PSI-Plot is nonfreeware then alternative free software are LibreCAD or FreeMAT or PSPP (as recommended by MagicBanana) and so on stuff.

Also using the same hook, if the original poster wants, please tell me
exactly what you want to do with the dataset, so I can try to help you
use GNU R for that.

PSI-Plot is not the operating system; Wine was meant to let us use misguided
applications, some developed long ago (like PSI-Plot, which I first used as an
inexpensive alternative to MathCAD with DOS 6.22). I have not yet found an
alternative plotting program, and PSI-Plot lets me produce professional grade
graphical representations of data, with proper line widths, readable lettering,
and the like.
At the time, I was an independent consultant working in a tiny business ... and
the fellow who developed PSI-Plot was also a small businessman who worked over
about the same period, eking out a living. Neither one of us could afford either
the time or spare cash for anything else. His product was proprietary in the sense
that it depended on the Microsoft operating system of the day; I needed his product
to prepare my results to my clients. No apologies.
In the meantime, I found a workaround: I copy and paste a column of cells at a
tine from LibreOffice Calc into the PSI-Plot spreadsheet opened with Wine, and
that approach lets me produce the needed graphical representations of my data.
I brought this up in the Trisquel forum because the Wine-assisted PSI-Plot
that I was using before Flidas came along worked passably well with the only
restriction that I must not sort on more than one column of a 50MB spreadsheet.
That is now impossible. Could it be that the subsequent updates of Belanos have
produced an interference with Wine/PSI-Plot ? We may never solve that problem.

Followup:
Magic Banana suggested a couple of graphical programs that are in the Trisquel repository.
One is mainly for statistical analysis; the other (SciDAVis) is more generally oriented,
so I have installed and will try that one out.
Thanks,

More followup ...
Made fifty individual graphs out of 800+ rows & a dozen columns of data from the
raw access files in a few hours ...now plodding through the task of resizing the
bitmaps to ready them for prime time as medium-sized JPG's and thumbnails (Gimp).
Had all fifty graphs and the original PSI-Plot spreadsheet open at once without
a hint of any memory crunch. It was the conversion from the LibreOffice Calc
spreadsheet to the PSI-Plot equivalent that ran into the out of memory error.
The graphs are all vector plots of GPS data showing signal paths .. all from April.

May I suggest some free (as in freedom) plotting software such as SciDAVis...
Indeed, my lab used to be locked in certain age-old proprietary (and also closed-source) junk software in order to do certain dirty jobs ("thanks to" the secret proprietary data file structure and format).
What I am doing is to completely redirect those old junks to /dev/null, by guiding the (collaborating) professors and post-graduate students (Ph.D. and M.S. candidates) to study and use exclusively free (as in freedom) software. Some of my Ph.D. students are fairly good at some of them.
Now my lab uses (but not limited to) the following free/libre software:
LibreOffice
GNU Octave
SciDAVis
Dia
Inkscape

SciDavis looks like a good match. My immediate task was to convert about a dozen
sets of two-step vectors into summarizing graphs ... nearly sixty such plots on
a recently finished webpage. Now that task is done (for the time being) and I can
think about using SciDAVis for the same purpose. The first step is obvious, but
adding the second step isn't. Off-list help would be much appreciated.
Another less pressing task (from a security standpoint) is to make graphical surveyor's
plats, where a number of vectors of different angles and lengths are daisy-chained
into a diagram of a piece of land ... for later comparison to aerial photographs.
