== VisTrails Overview ==<br />
<br />
Recently, workflows have been emerging as a paradigm for representing and managing complex <br />
computations. Workflows can capture complex analyses processes at various levels of detail and <br />
provide the provenance information necessary for reproducibility, result publication and result <br />
sharing among collaborators. Because of the formalism they provide and the automation they <br />
support, workflows have the potential to accelerate and transform the information analysis <br />
process. Workflows are rapidly replacing primitive shell scripts as evidenced by the release of <br />
Apple’s Mac OS X Automator, Microsoft Windows Workflow Foundation, and the SGI <br />
Scientific Workflow Solution. <br />
<br />

VisTrails is a new scientific workflow management system developed at the University of Utah that <br />
provides support for data exploration and visualization. Whereas workflows have been <br />
traditionally used to automate repetitive tasks, for applications that are exploratory in nature, very <br />
little is repeated---change is the norm. As an engineer or scientist generates and evaluates <br />
hypotheses about data under study, a series of different, albeit related, workflows are created <br />
while a workflow is adjusted in an interactive process. VisTrails was designed to manage these <br />
rapidly-evolving workflows. VisTrails streamlines the creation, execution and sharing of complex <br />
visualizations, data mining or other large-scale data analysis applications. By automatically <br />
managing the data, metadata, and the data exploration process, VisTrails allows users to focus on <br />
the task at hand and relieves them from tedious and time-consuming tasks involved in organizing <br />
the vast volumes of data they manipulate. VisTrails provides infrastructure that can be combined <br />
with and enhance existing visualization and workflow systems. <br />
<br />
Although VisTrails was originally built to address the needs of exploratory scientific applications, <br />
the infrastructure it provides is very general. This became clear as the system was demoed to <br />
people from different domains, both from industry and academia. VisTrails has the potential to <br />
reduce the time to insight in virtually any exploratory task.<br />

==Rev 674==<br />
On Linux machines using PyQt4.2, there is a bug that causes vtk pipelines not to show on the spreadsheet.<br />

==Rev 559==<br />
There are two issues with the binary version of this release.<br />

<br />
'''2. When installing on a non-english system or on a custom directory, VisTrails won't start. This is due to absolute paths inside the bookmarks file.'''<br />

==Rev 674==<br />
On Linux machines using PyQt4.2, there is a bug that causes vtk pipelines not to show on the spreadsheet.<br />
Solution: edit the file <code>path_to_vistrails_src/vistrails/packages/vtk/vtkcell.py</code><br />
<br />
in the import section (around line 27), add<br />
import sip<br />
replace line 244:<br />
vp = '_%s_void_p' % (hex(int(QtGui.QX11Info.display()))[2:])<br />
<br />
by<br />
<code><br />
try:<br />
vp = '_%s_void_p' % (hex(int(QtGui.QX11Info.display()))[2:])<br />
except TypeError:<br />
#This was changed for PyQT4.2<br />
if isinstance(QtGui.QX11Info.display(),QtGui.Display):<br />
display = sip.unwrapinstance(QtGui.QX11Info.display())<br />
vp = '_%s_void_p' % (hex(display)[2:])<br />
</code> <br />
<br />
==Rev 559==<br />
There are two issues with the binary version of this release.<br />
<br />
'''1. When the current directory is not on the PATH. This causes VisTrails to raise a ''Requirements not fulfilled exception''. '''<br />
<br />
'''Solution:''' Adding '.' or <code>path_to_vistrails_install/vistrails</code> to the PATH solves this problem.<br />
<br />
'''2. When installing on a non-english system or on a custom directory, VisTrails won't start. This is due to absolute paths inside the bookmarks file.'''<br />
<br />
'''Solution''': Remove file <code>bookmarks.xml</code> inside <code>~/.vistrails</code> folder. On Windows XP it's located on <code>C:\Documents and Settings\your_username\.vistrails</code>. On Windows Vista, it's located at <code>C:\Users\your_username\.vistrails</code>.</div>Draperghttps://www.vistrails.org//index.php?title=Known_issues&diff=1070Known issues2008-06-23T21:45:38Z<p>Draperg: /* Rev 559 */</p>
