Therefore your notebook cannot allocate so much memory. For instance, with a 4ms sampling rate, a 32bit precision (float), and a 6 seconds trace length, loading your lineset requires 576 Mo per attribute! So you can understand quite easily that this is not doable on your notebook. To overcome this, two solutions are possible (and combining them would be optimal): - Increase the amount of memory on your system. This is one of the few upgrades that can be easily performed on a notebook by any user. We would recommend 2GB, especially when working with 2D data. - Upgrade your graphic card to a generation that supports shading. When shading is enabled, the textures are allocated within the graphic card's memory, and not into the system memory. Nevertheless, graphic cards also have various amounts of memory, ranging from 128 to 1024Mo within a single generation of GPUs, so care must be taken with respect to this. We recommend nvidia graphic cards from generations 6, 7, or 8 (latest), with at least 256Mo of dedicated memory (320 or 512 is better). Although AMD (previously called ATI) GPUs (X1xx and X2xx generations) support shading on the hardware side, they did not yet develop Linux drivers to use it. Concerning the line spacing, there is no option to handle this. This is simply because the horizontal spacing is determined by the bin size (survey geometry in general), and the amount of zoom (in or out) you apply. The only solution to see two lines placed very close to each other at the same time would be to load them into two 2D viewers.

I was wondering, because it's kind of difficult to find a suitable nVidia video card for my notebook in general and I need to work with several big seismic data sets, if you know (or someone else in the list) a desktop with optimal features for this type of jobs, i.e., there are lots and lots of good computers out there but may be people who have years and years of experience working with 2- D and 3-D seismic data sets prefer ones especially, it would be great to know which computer could handle this kind of work and get it. Besides, for OD stablilty (without crashing), which operating sytem would you recommend? windows or linux? With Best Regards, Gery. P.S.: I found this surfing on internet, http://www.directron.com/aspectx1.html, would it work?

This is why we moderate the users group - it's a typical thing for support at opendtect.org. If you're interested: in the past days there has been extensive contact with Simon and we now at the level of investigating his OpenGL drivers (he's using a Matrox Millennium G550 card. It seems the driver for that card is not actually used). One thing that may be of interest is the description of the problem. I think Simon already did a much better job than usual. Still, we usually like to know *exactly* what goes wrong where. In this case it's very interesting to know when the crash appears: (1) Immediately when you select the cube name (2) During the progress of loading (3) When the loading is finished but before you see anything (4) You see something appearing and then it crashes In hist case, it was (3) which pointed us towards his graphics card drivers. - Bert -- -- Bert Bril / OpendTect developer at dGB -- Nijverheidstraat 11-2, 7511 JM Enschede, The Netherlands -- mailto:Bert.Bril at opendtect.org , http://opendtect.org -- Tel: +31 534315155 , Fax: +31 534315104 From jflocks at usgs.gov Thu Sep 20 17:03:08 2007 From: jflocks at usgs.gov (Jim Flocks) Date: Thu, 20 Sep 2007 11:03:08 -0400 Subject: [Users] Mac users, any luck displaying numerous seismic attributes? Message-ID: Hi, In response to an earlier post, OpendTect will operate on a Intel/Mac, but is limited. It appears the Intel Mac has a problem displaying large or numerous seismic lines. I cannot display the seismic attributes on more than two 2-D seismic lines at a time. However, numerous (14+) seismic lines display just fine on a slower non-Intel PowerPC, with less RAM. Unfortunately the PowerPC cannot be used to create horizons. RAM fills and it crashes. I tried several Mac configurations, details are below. Just today tried a Dual Core with more memory and a faster graphics card, and even tested running Windows XP using Parallels, to no avail. I know the project is o.k. because it displayed on a Dell PC running windows XP (and on the slower PowerBook). So, for me, doesn't look like I can take full advantage of OpendTect yet: either get full display (PowerPC), or the ability to draw interpretations 1 line at a time (Intel-Mac). Has any other Mac users had better luck? Has anyone tried a 2+ GHz, older PowerPC with lots of memory running OpendTect 3.0? Thanks, Jim Test details: 450 MHz Power PC G4 (OS 10.3x, OT 2.4) - OpendTect will not operate 1.25 GHz Power PC G4 PowerBook (OS 10.3x, OT 2.4) - will operate nicely, cannot create horizons 2-2.6 GHz Dual Core Intel Mac Pro (OS 10.4, OT 3.0) (1GB memory) - will operate, can create horizons, but will not display large or numerous seismic lines. Same config as above but with more memory and faster graphics card: (2GB memory, ATI Radeon X1900XT, 512MB VRAM) - will operate, can create horizons, but will not display large seismic lines.

In-Reply-To: References: Message-ID: Hi I now installed OD 3.1.4a on intel Mac (3GB memory, ATY RadeonX1600) with Mac OS X 10.4.10 and tried to open a couple of 3D files and 2D files at my hand ( 5 sec at 2msecSR, 400 CMPs/file). I could do. But I guess you mean 'numerous' by more or much longer sections. System requirement seems to be Mac OS X 10.4.4 for OD 3.0 now (ftp:// ftp.opendtect.org/pub/rel/hardware_requirements.html). I am not sure what is the OS requirement for older version of OD. One thing to firstly try would be to update OD and OSX 10.3* to OS X 10.4.4 or more for Power PC Mac and display large files as OD is coded by PPC native. Clock speed would not be so essential if you are patient.

Or for instance, apply an opacity filter to display only certain amplitude values? Let me answer to this questions. Yes, this is possible in OpendTect: First, you need to have access to the amplitude histogram; This is achieved by selecting the attribute in the tree scene, moving the cursor over the colorbar, right-click and press edit. This will pop-up the colourbar editor, which always shows the histogram of the selected attribute in grey on the top right corner of this window. The X-label of this histogram is represented by the amplitudes shown on either sides of the colourbar in the main window. Now that you have access to this histogram, you can apply an opacity filter by adding nodes where the histogram is shown. This transparency function as we call it is displayed using a red line joining the nodes (two nodes are always present, although they can move up and down). The more the transparency (red) curve is to the top, the less the corresponding colour will be shown. As many nodes as needed can be added with a double click. The result of any editing will be applied directly. There is no need of going out of the colour bar editor. Please note that some default colorbars (like Chimney) already have a transparency function integrated. We are currently developing a more sophisticated histogram tool, which is available in our development release 3.1.4a (http://download.opendtect.org). A specific button "Show histogram" is available in the menu when making a right-click on an attribute in the tree.

More sophisticated extraction tools are available in other commercial software packages. Concerning the inversion to impedance, you can already apply seismic coloured inversion in OpendTect, using the plugin made by ArkCls. In order to get an absolute impedance volume, ArkCls and Earthworks Environment & Resourced Ltd (http://www.sorviodvnvm.co.uk) released a beta version of a brand new impedance inversion plugin. This latter includes a deterministic model based inversion algorithm, kriging tools and a Multi-Point Stochastic Inversion algorithm. More details can be found on their website.
