The WFDB Toolbox for MATLAB/Octave is a collection of functions for reading, writing, and processing physiologic signals in the formats used by PhysioNet (see README for details).
Long record names are not parsed properly by ecgpuwave resulting in failed annotations. I have discovered the issue on the PhysioNet ECGRDVQ database, where the record names have a form XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX.<dat/hea> that is also prepended by the path name of ecgrdvq/raw/10[01-22].
To reproduce:
run ecgpuwave on the 1st record in the ecgrdvq database by:
The resulting annotation file is ecgrdvq/raw/1001/00ed2097-cd14-4?.ann. Note the question mark ? in the file name. So, the full file name without the extension and ? is 32 symbols long. (The non-Matlab (Unix-based) version of ecgpuwave returns a similar result.)
which seems to be limiting the length of a record name. Simple change to:
character*64 arg, f, fname, desc, units
solves the problem.
P.S. I do not know where to file the issue, as it seems being an issue
for ecgpuwave not the toolbox itself. However, there is no issue
tracking system for the original Fortran code of ecgpuwave.
Additionally, I could not find any similar issue on other or even the same database, although it seems to be quite easily discoverable (no one annotating ECGRDVQ database ever?).
Another solution would be to rename all the files in this particular database (>5000 records), which is quite unreasonable in this case.
