When I use it, it only draws the box all around the strip, but not the subticks inside it. The rest of the output seems to be OK. I'm running the WFDB software package under Knoppix, v. 3.7. And the version of the WFDB is 10.3.14. I've been looking the grid procedure in the pro file but I don't understand it that much as I don't know anything about postscript procedures. I would appreciate any help I can get on this. Thank you.

It's likely that the grid lines are being drawn, but are not visible, because pschart draws them as narrow as possible (by setting the PostScript line width to zero). Your printer may render such lines nearly invisibly. I originally wrote pschart for use with an Apple Laserwriter, which had a resolution of 300 dpi. The Laserwriter produced a thin but legible "zero-width" line, and did so *much* faster than it was able to render any wider line. For this reason, pschart's default line width was set to zero. Modern printers have considerably better resolution and much faster rasterizing engines, so pschart can draw wider lines on them without any significant speed penalty. Use pschart's -w option to choose a suitable line width. I get good results using -w 0.2 on a variety of printers. (The argument following -w is the line width in millimeters.) In the next release of the WFDB software package (10.3.17), the default line width for both pschart and psfd will be 0.2 mm.

So i created matlab scripts wich convert '.dat' files to recover directly signals based on the work of Tratnig and Rheinberger. These are 2 scripts for ECG databases (MIT-BIH Normal Sinus Rhythm Database and Post-Ictal Heart Rate Oscillations in Partial Epilepsy) and one script for multi-parameter database (MIT-BIH Polysomnographic Database) They can be easily modified to fit other databases. There is just a memory problem still to resolve for Polysomnographic database when there are more than 4 signals and a long recording duration. I think this could be useful for matlab users who want to use their own algorithm on the database. I propose them for download from physionet. Obtained signals in matlab format were controlled to have the same values as signals obtained with physiotools. Moreover, i noticed a problem, in polysomnographic database, in slp02a and slp02b as they have the same first values. With physiotools, i had other values for slp02b ([-109 165 116 70] instead of [4 41 -70 4] which corresponds to slp02a). I have already send a mail for contributions but didn't receive any reply.
