Sometimes I get this message from OPUS and I'm not doing anything different I don't think from when the file processes! What am I doing wrong?

?ÿ

The file 3957_2.21o seems to have a collection interval of 4 seconds!ltbrgtThe collection interval must be 1,2,3,5,10,15 or 30 seconds to be processed by OPUS.

Can you open the file with a text editor and confirm the times are spaced properly?

Rename an extra copy of the file *****.txt if that helps find a program to open it.

As Bill93 notes, Take a careful look at the first six time epochs to make sure they match the sample rate you expect and there was not a drop out. Someone once told me that OPUS is picky about the initial five measurement set to establish the sampling rate. If the decimation rate is not consistent over the full file, bad things also happen.

Aside, I use Notepad++ to edit these or any other large files, much faster than generic Notepad and has a number of useful plug-ins to highlight all sorts of things.?ÿ

Wait and send again. Happened to me two days ago.?ÿ I no longer think OPUS error messages have anything to do with the actual error.?ÿ

as was noted above:?ÿI??ve gotten that several times. And if the interval 15 seconds BUT the first 1-3 epochs are not 15, it quits. I delete the first several epochs in the rinex file and edit the time of first obs in the header.?ÿ
