Hi Mark,
Thank you so much. I resolved first two issues. But I'm still working on the last one 'eigerDetector crashes EPICS IOC' ( e.i. Segmentation fault (core dumped) )
I wasn't able to find where it crashed. The following is the message I've got.
Note that the version of areaDetector, ADEiger, ADCore and EPICS base are R3-7, R2-7, R3-8, 3-15-6, respectively.
We're using FileWriter interface to save data files.

You have not told us what version of ADEiger, ADCore, EPICS base, etc. you are using.
Ø a) It keeps failing to open 'sseq_setting.req' file (Purple in the following message)
Did you uncomment this line from ADCore/iocBoot/EXAMPLE_commonPlugin_settings.req? #file "sseqRecord_settings.req", P=$(P), S=AcquireSequence
If so you also need to uncomment this line from ADCore/iocBoot/EXAMPLE_commonPlugins.cmd #set_requestfile_path("$(CALC)/calcApp/Db")
Ø b) It keeps failing to writing 'auto_settings.sav' file (Blue in the following message) Ø ../save_restore.c(1774): [0xd]=write_it:Permission denied
That error seems pretty simple. It is a file permission problem. The files in that directory, or the directory itself, must not have write permission for the account that is running ADEiger application. Fix the file permissions.
Ø c) When the data acquisition is done on eigerDetector, it crashes EPICS IOC (Red in the following message) Ø
Actually data hasn't been collected
You have a core dump file. You need to run gdb on that to find where it crashed. Run this: gdb /path/to/ADEiger_executable core.xxx
where core.xxx is the name of your core dump file. Once you get the gdb> prompt type this command backtrace

On Behalf Of Jong Woo Kim via Tech-talk
Hello,
When the data collection is done on 'eigerDetector.adl', EPICS IOC is crashed and actually data hasn't been collected. In addition, whatever parameters I changed on 'eigerDetector' are not applied in autosave. These are the summary followed by the message.
a) It keeps failing to open 'sseq_setting.req' file (Purple in the following message) I made sure that this file has contents and it is in a right folder support/calc-R3-7-3/calcApp/Db/sseq_settings.req support/calc-R3-7-3/db/sseq_settings.req
b) It keeps failing to writing 'auto_settings.sav' file (Blue in the following message) It keeps trying to save settings every 30 second as it is set on the first purple line. But it can't.
c) When the data acquisition is done on eigerDetector, it crashes EPICS IOC (Red in the following message) Actually data hasn't been collected
