Thread: sac file merge problem

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!
