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 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 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.

What are Excel (.xls) files and how do I read them?

Primary Resources: FAQs
Excel (.xls) files are documents that have been created using Microsoft Excel. If you don't have Microsoft Excel then many other spreadsheet packages open Excel documents. Alternatively you can download the free Excel viewer from Microsoft Office Online. Search for Excel viewer. Many of the Excel files on this site use macros to provide interactivity. We recommend that you scan all downloads with an up-to-date virus checker before using them, particularly when you enable features such as macros.

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 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 ?
