Frequently Asked Questions

How can I use Matlab's import feature to read signal files?

Frequently Asked Questions about PhysioNet
You can't in general, because Matlab doesn't know how to figure out which of the many supported formats is used in any given signal file, because it can't understand the most commonly used formats in any case, and because (in many cases) signal files are orders of magnitude larger than any matrix that Matlab can handle. See How can I read signal files? for a variety of ways to read signal files from Matlab without using its import feature.

How can I use Excel's import feature to read signal files?

Frequently Asked Questions about PhysioNet
You can't, because Excel doesn't know how to figure out which of the many supported formats is used in any given signal file, because it can't understand any of those formats in any case, and because signal files are almost always orders of magnitude larger than any spreadsheet that Excel can handle. Spreadsheets are not suitable for studying, visualizing, or analyzing digitized signals; many better tools are freely available in PhysioToolkit.

How can I read signal files?

Frequently Asked Questions about PhysioNet
If you would like to read signal files within a C, C++, Fortran, Java, Perl, or Python program, see the WFDB Programmer's Guide for information on doing this using the WFDB library. Other programming languages supported by SWIG may also be usable with the WFDB library, but have not been tested. Briefly, use isigopen() to open the files, and getvec() to read them.

How can I import MATLAB graphics into my Framemaker, TeX, etc. document?

MATLAB Frequently Asked Questions
The MATLAB (version 4) print command provides a "-deps" argument which provides a Encapsulated PostScript file of your plot. Some people have reported various problems getting this stuff to work. Some suggestions: Use "bbps" and ghostscript. "bbps.shar" is available via anonymous ftp on "csi.jpl.nasa.gov". You'll need to get GhostScript from your nearest GNU ftp site.

What is the format of the signal files?

Frequently Asked Questions about PhysioNet
Many formats are supported. Most signal files are written in "format 212", in which two 12-bit samples are bit-packed into three 8-bit bytes. See signal(5) in the WFDB Applications Guide for details on format 212 and on the other supported formats. To determine which format is used for a given signal file, look in the associated header file. (This is a text file that usually has the same name as the signal file, except for a suffix of .hea instead of .dat.

Can I import other documents/files into Web4Print?

Web4Print frequently asked questions (FAQ): client-server sy...
To bring text into a Web4Print text frame, just cut and paste directly from a word-processing document. You can also import EPS, TIF, JPG, GIF and BMP files and treat them as images/objects within a Web4Print document.

Can a model saved as an applet use import-world, file-open, and other commands that read files?

NetLogo 3D Preview 5 User Manual: FAQ (Frequently Asked Ques...
When running my model as an applet, I get the following error: java.lang.OutOfMemoryError: Java heap space. When I tried loading my model as an applet I get an error like: java.lang.ClassFormatError: Incompatible magic value.

Can I use C and Fortran programs with MATLAB?

MATLAB Frequently Asked Questions
MATLAB's MEX-file facility allows user to use C and Fortran subroutines as MATLAB m-files. It is also possible to use MATLAB as a computational engine for C/Fortran subroutines.

Why do we use MATLAB?

CS100M FAQ
We wish to expose you to another high level language. CS100 teaches programming, not just specific languages. So, skills you learn in Java should transfer to other languages. MATLAB offers a very powerful and elegant language for performing numerical analysis. We encourage you to explore similar packages, such as Maple, Mathematica, MathCad, and TKSolver.

Can PSIM read SPICE files or import SPICE models, or vice versa?

Index
No. Even though PSIM netlist files are similar to SPICE netlist, the way that a circuit is set up is different. For example, only logic signal (0 or 1) is needed to drive a switch in PSIM. In SPICE, however, the gating signal must be sufficiently large to turn the switch fully on.

My old logbook program use dBase files (.DBF). Can I import them to VQLog ?

VQLog - Frequently Asked Questions (FAQs)
Open you DBF file into MS-Excel, remove the first row which contains the field names and save it as a "Formated text - delimited by spaces (*.PRN)" file type. If you need to import some specific fileds (Power, rig, etc.) not supported yet by VQLog's ASCII importation then you still have the option to do the importation in two steps There is also a free program called DBFToADIF that converts some old DBF log files to ADIF.

How can I read annotation files?

Frequently Asked Questions about PhysioNet
If you would like to read annotation files within a C, C++, Fortran, Java, Perl, or Python program, see the WFDB Programmer's Guide. Other programming languages supported by SWIG may also be usable with the WFDB library, but have not been tested. Briefly, use annopen() to open the files, and getann() to read annotations from them.

How do I read the download files on this website?

Frequently Asked Questions (FAQs)
pipe-delimited text (.txt) format files (OTCBB Symbol Directory, Daily List, Monthly Share Volume, etc.); self-extracting ZIP (.exe) files that expand into pipe-delimited text format files (Monthly Share Volume Report, Market Maker List, Other-OTC Symbol Directory, etc.). This information will need to be saved to your computer. Select File from the menu bar, then select the Save As... option You can now import the data into a spreadsheet or database.

Why are some files in PDF format, and how can I read them?

FRB: FAQs
Adobe's Portable Document Format (PDF) reproduces the exact look of a printed page and is used for documents that could not be readily deployed in hypertext markup language (HTML)--the "typeset" format that is designed for web browsers--or in the plain "typewriter" text of ASCII (American Standard Code for Information Interchange). Also, the document may be offered in PDF along with one or both of the other two formats.

Can YSI import Camera Raw Files?

YSI - Frequently Asked Questions
If you are using PhotoShop CS and have the appropiate raw file plug-in, YSI will import Camera Raw Files. The Raw file conversion will only engage when you export a finished layout direclty into PhotoShop or Batch process all files as PSD's. Each image within a aperture will be prompt for conversion as the layout is built.

How can I import many files at once?

The Import Files dialog allows you to select multiple files provided you are running Python 2.3 or above. There is also an importFiles script in LeoPy.leo. You can use that script as follows: import leoImport leoImport.importFiles(aDirectory, ".py") This will import all .py files from aDirectory, which should be a full path to a particular directory. You could use ".c" to import all .c files, etc.
