Hi people of the EDF group, here is Martin, a Spanish investigator at the Universidad Politécnica de Valencia. We started some time ago working on EEG signals...
Martín, I forgot to ask last week: did you try the EDF compatibility checkers on www.edfplus.info (click downloads) and http://www.teuniz.net? If the header...
Thanks Mr.Bob and Mr.Patrick for your fast response, Bob: I did not try those conversors, but i will try them now. I was working with the codified signal in...
BESA can export to ASCII or to EDF+. In the official BESA release, you can only read Deltamed files if you have their dongle. With the new version that's not...
Hello, In a Dec. 12, 2005 posting, Bob Kemp refers to the URL http://www.hsr.nl/edf/contact/guidelines.html for finding the data record duration. This URL no...
The new URL of the EDF website including the specs is: http://www.edfplus.info The datarecord sizelimit of 61440 bytes is a recommendation in EDF but it is...
Hello Teunis, It was good of you to respond so quickly. This is what I understood from the EDF/EDF+ specifications and appreciate your confirmation. It is not...
"It is not necessary for software to confirm or even check the data record duration limit when reading from EDF/EDF+ data files." I agree. "I may be missing...
... invented ... This is not a reasonable explanation. If the data file is small then this would be a perfectly acceptable way of storing data. A 61440 data ...
... It accomodates computers/software that do not support a flat memory model. If there are any such computers running today then there are indeed very few...
Quoting: The EDF+ data records contain the ordinary signals according to the EDF specs (including the size limit of 61440), except for the fact that the data...
We updated our EDF checker on http://www.edfplus.info/downloads/software/edfchecker.zip It now specifies the size of the datarecord if it exceeds the 61440...
I need to create a EDF file which allows me to index data samples with sub-second resolutions (a lá POSIX). E.g., "recording start time: 23:12:32.17634" ...
... with sub-second resolutions (a lá POSIX). E.g., "recording start time: 23:12:32.17634" ... one solution is to "hide" the fractional part somewhere else in...
This checker interprets the recommendation as a specification. The 61440 limit is recommended for EDF and obligatory in EDF+. Of course, if we could specify...
EDF+ solved this problem. Just like EDF, it has a starttime like 23.12.32(not 23:12:32) in the header. But in contrast to EDF, its datarecords need to be...
... datarecord has ... This solution will only work with software that is EDF+ compliant. Software that is EDF compliant but not EDF+, will still have the ...
Liebe Freunde, Ich habe den Eindruck dass diese Aktion weltweit wohl ein Sturm verursachen kann, wenn jetzt alle Leute immer mehr verstehen, das Sie selber die...
version 1.03 changes: - improved printing resolution - solved an issue with printermargins and fonts thanks to new printerframework in Qt 4.4.x - added option...
Hello! I'm a student at the TU Berlin writing my master thesis about a Personal Health Care System. We are currently looking for an appropriate file format for...
Thanks a lot for the papers! I can finally write EDF+ files including EVENTS ;-) Also the EDF compatibility check which is included in the EDFbrowser is really...
Good evening, Do the minimum/maximum physical values refer to the input (voltage) range of the recording device or the range of the actual data values. For...
Quoting the EDF specs: "The digital minimum and maximum of each signal should specify the extreme values that can occur in the data records. These often are...
... Wrong, if the amplifier gain is 10000 and the maximum input voltage of the A/D-card is +/-10V then the analog input range is +/-1mV. ... You have two...
