What is an annotation?
Frequently Asked Questions about PhysioNetInformally, an annotation is a note about some feature of a signal.

Should I use code- or annotation-style aspects?
AspectJ Frequently Asked QuestionsTo use AspectJ, you can use the original code-style aspects or the annotation-style aspects new in AspectJ 5. The original code-style is a small extension of the Java language designed to express crosscutting as clearly as possible in ways familiar to most Java programmers. To use the original code-style aspects, compile them with the AspectJ compiler or weave pre-compiled binary aspects using the AspectJ binary (.class) weaver, either at build-time or at class-load-time.

In your META-INF directory, add the EJB reference in the application-client.xml file that specifies the EJB you want to refer to. In release 1.0.2.2 we support pessimistic locking and an implicit read-only mode (only changed fields are written. See similar questions...
What is the format of the annotation files?
Frequently Asked Questions about PhysioNetMost annotations occupy two bytes, of which 10 bits contain the interval (in sample intervals) from the previous annotation, and 6 contain an annotation type code. Special type codes allow for annotations at intervals that exceed 1023 sample intervals, and for other numeric and text fields to be associated with individual annotations. See annot(5) in the WFDB Applications Guide for details. See similar questions...
How can I read annotation files?
Frequently Asked Questions about PhysioNetIf 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. See similar questions...
What are some common annotation errors to avoid?
It should be noted that annotations (apart from the biosource of the sequence (i.e., Homo sapiens, Arabidopsis thalania)) are not mandatory in an HTG record, and submitters should not feel obligated to add them. Listings of computer-generated repeats add little to the record because it is fairly easy to find these repeats on a DNA sequence. However, if you want to add experimentally or computationally derived annotations to the sequence, we welcome them. See similar questions...
Can I use your annotation capabilities on my collection of JPEG files?
FAQ - Neuroinfo Virtual SlidesYes. The viewer can load and pan around .jpg files by loading the entire image at once. The annotation and quantification tools are identical to those used for virtual slides. This enables researchers who already have large collections of photomicrographs to use the collaboration and quantification capabilities of Neuroinfo. Yes. We are completely compatible with Zoomify file formats, viewers and annotations systems. See similar questions...
