In the 1 step of the calculation, there are some error--logger: checksum error in 'M' packet that i don't known what's the meaning. And the problem is also in the step 2. When i ignore these and came to the step 3, the solution is "nan". I'm really confused.


the solution of step 1:

post your log files (via e.g. dropbox), are you using aimu or dimu ?

The errors indicate possible corruption or bad data in the static log file. Did you trim the ends off that log as described in the wiki? Do you have another static file (from different freeze/thaw) to test with?

You could also post screenshots of the relevant graphs from the static log. Uploading the huge static file could take a while. But if you do that, at least compress (zip) it first.

Hello! I ran into exactly the same problems as you did, and I have no idea about how to handle it.
Firstly I had both the 'checksum error in 'M' packet' problem and the '+nan' problem. Then after I tried trimming off the head and end of static files, the 'checksum error in 'M' packet' gone, but there were still '+nan' in the third step.
Would you like share with me how you solved the problem?
