Hello,<br><br>My name is Lepolt Linkimer, I am a PhD student at the Department of Geosciences at the University of Arizona. I am in the process of detecting and
associating local earthquakes using data from both the SIEMBRA and ESP
experiments in the Argentinean Andes. I have a total of 52 stations and the seismicity in this region is *very high*. I am interested in detecting possibly all local earthquakes. I have been having the following error when running dbdetect for the entire dataset:<br>
<br>command line: dbdetect -v -pf /arc6/lepoltl/<a href="http://dbdetect.pf">dbdetect.pf</a> SIEMBRA_db SIEMBRA_db<br><br>Attached the pf file I am using.<br><br>Error:<br>------------<br clear="all">dbdetect: Can't mmap table 'SIEMBRA_ESP_db.detection'.<br>

<br>I am using antelope 4.10 and I believe all patches have been applied.<br><br><font face="Bradley Hand ITC TT-Bold"></font>The error occurs when the output file "SIEMBRA_ESP_db.detection"
reaches a size of exactly 1022Mb. Is there any limit of filesize for
the output? Is this file size "normal". I have decided to run the
detections by periods of time and I ended up with 8 detection tables
(the project is two years). dbdetect works fine for me unless the
output reaches 1022 Mb. I am now running the associations (bdgrassoc)
for each detection table but I am wondering if this approach will give me
complications in the future. What do you think?<br><br>Thanks for your help!<br><br>Lepolt<br>-- <br>PhD Candidate<br>Department of Geosciences<br>University of Arizona<br><a href="http://www.geo.arizona.edu/~linkimer/">http://www.geo.arizona.edu/~linkimer/</a><br>
