Generating your nvflash blob files To gain access to nvflash you will need to generate nvflash blob files which will allow you to authenticate with the APX mode on device.
To begin please download the file suitable for your OS and tablet from the download section. Accessing nvflash Finally, you will now be able to access nvflash using wheelie. Good news! You have acquired nvflash access so what should you do next? DAVE is an integrated environment for the reduction, visualization and analysis of inelastic neutron scattering data.
It offers generic visualisation, and domain specific processing. The GDA project is an open-source framework for creating customised data acquisition software for science facilities such as neutron and X-ray sources. It has elements of the DAWN analysis workbench built in. Gumtree is an open source project, providing a graphical user interface for instrument status and control, data acquisition and data reduction.
IDL is a high-level technical computing language and interactive environment for algorithm development, data visualization, data analysis, and numeric computation.
IGOR Pro is an extraordinarily powerful and extensible scientific graphing, data analysis, image processing and programming software tool for scientists and engineers. ISAW can be used to read, manipulate, view, and save neutron scattering data. The Mantid project provides a platform that supports high-performance computing on neutron and muon data.
MATLAB is a high-level technical computing language and interactive environment for algorithm development, data visualization, data analysis, and numeric computation.
The goal of NeXpy is to provide a simple graphical environment, coupled with Python scripting capabilities, for the analysis of X-Ray and neutron scattering data. It was decided at the NIAC meeting that a large portion of this code would be adopted in the future by NeXus and be part of the distribution. PyMca is a ready-to-use, and in many aspects state-of-the-art, set of applications implementing most of the needs of X-ray fluorescence data analysis.
It also provides a Python toolkit for visualization and analysis of energy-dispersive X-ray fluorescence data. Note the h5toText tool mentioned here previously is no longer available from the spec2nexus project.
Here are some of the generic tools that are available to work with HDF files. In addition to the software listed here there are also APIs for many programming languages that will allow low level programmatic access to the data structures.
There are various command line tools that are available from the HDF Group, these are usually shipped with the HDF5 kits but are also available for download separately. Collected here are some of the tools identified 5 as a result of a simple question asked at the Nobugs conference: Are there examples of code that reads NeXus data?
Before continuing, I suggest getting a backup blob using Flatline of the entire Nexus 7 device. If I had known about this earlier, it could have saved me a lot of headache during an update. See the article here. Click start and paste this in: cmd. Then, also extract the image-nakasi-ktu84p. Each command is on a single line. Next, enable developer mode and USB debugging.
Open Settings 2. Scroll down to the System section and tap About tablet 3. Go back to settings and tap on the new Developer Options item 5. When prompted to allow, tap OK. Connect your Nexus 7 to the USB port on your computer. Press OK to allow the connection. Start by making sure the device is being read properly. From your command prompt, run this command: adb devices If all goes well you should see the device ID listed like so:.
Next, we will need to unlock the bootloader with this command: adb reboot bootloader The nexus should reboot into a bootloader menu — You may hear the Windows sound indicating a device was disconnected, then reconnected. This is normal. That is to say that the FileTypeAttribute is assigned when you upload a blob from a Web Interface a Web Transaction , a procedure or a Business Component in a batch mode from a procedure.
The default value is none , stating that no attribute holds the file type. Constraints on the FileTypeAttribute:. Note: If the FileTypeAttribute property is assigned with a value, the corresponding attribute assigned to this property cannot be explicitly modified through a web transaction.
As we've already explained the FileType property , let's now look at the FileType runtime property. FileType The FileType property returns the actual file extension, when the blob is being uploaded. FileType if not Attblob. FileType returns the actual file extension. When the file is being downloaded, the FileType is obtained from: 1. The FileType property, if it's assigned in the design model. The FileTypeAttribute property of the blob if it has one.
Otherwise, it returns null. A Blob data type attribute can store files. The attribute stores the file content but not it's original name. You should set this property if you want to keep track of the original file name. Every time the Blob data type attribute is assigned either in the user interface or by an assignment command the value of the FileNameAttribute is also automatically assigned. The default value is none , stating that the original file name is lost.
Constraints on the FileNameAttribute:. Note: When downloading the file, it is temporary saved with its original name which is taken from the FileNameAttribute , plus a random number. So that each file is given a different name, in order to be able to run the application in multiuser and concurrent environments.
Content Types are a means of identifying web pages, images, and multimedia files on the Web and in email messages. They allow web browsers and email clients to display content in a correct and safe way. In the case of blobs, it may be necessary to set their Content Type, especially for certain kind of files, or for certain Internet navigators. It's important to note that GeneXus automatically generates the corresponding Content Type of each blob, based on the extension it has. But there are ways to change this Content Type, if the user wants to.
There are two ways to do this in GeneXus:. ContentType property design and runtime control property. It indicates the content type that should be associated with the Blob.
For example, the content type of. The Content Type depends on the browser, and that's why the GeneXus user is given the possibility of setting it programmatically.
However, the corresponding Content Type is actually determined at runtime by the generated program. That is to say, in most cases you only need to set the File Type properties or nothing at all, if the blob has a FileTypeAttribute associated to it.
This is because GeneXus automatically determines the Content Type, from this information. The ContentType Property should be used when the extension doesn't allow unique identification of the Content Type, or when the GeneXus user wants to set it depending on the end user's browser. You can query the name of the file by using the FileName property runtime property. This is a ReadOnly property, which allows you to know the name of the file associated to a blob.
