[SAC-HELP] sac file merge problem

[Dylan Mikesell]

Has anyone ever had a problem with merging a lot of data. I have 5 days 
of data recorded at 250 Hz. The files were acquired and saved in 30 
minute intervals. I am now trying to merge all the half hour sections 
into one file. The merge function seems to work fine until I get to the 
3rd day, but after that the data starts to look corrupted and gets 
choppy. It kind of looks like the trace has been down-sampled.

If I look at the individual traces before merging the data look fine. I 
am wondering if SAC can't handle the size of the merged file. After 
writing the merged file it is almost 500 MB. The individual 30 minute 
sections are 1.8 MB.
Thanks for any help!
