how can i open the message catalog in matlab? i am using the sptool.m file in toolbox/signal. in getstring(message('signal:sptprefhelp:Maker')) if i change 'Marker' to 'Markers' it warning:unable to find message key 'Markers' in catalog 'signal:sptprefhelp'. where can i check or find the message keys?

When you see
then examine the file
fullfile(matlabroot, 'resources', 'signal', 'en', 'sptprefhelp.xml')
It will have a number of entries, such as
<entry key="ByClickingOnACategoryThePanelOnTheRightChangesToReflect">By clicking on a category, the panel on the right changes to reflect the preferences for that category.</entry>
Look for the one for which key=" matches the last component of the message identifier, Maker in the case of your example. So you would be looking for
<entry key="Maker">SOME TEXT HERE</entry>
In R2017b, neither "Maker" or "Marker" appear in that file, but "Markers" does:
<entry key="Markers">Markers</entry>
The 'en' part can instead be 'ja_JP', 'ko_KR' or (sometimes) 'zh_CN' for the messages localized to Japanese, Korean, or Chinese.

You shouldn't need to access or update the message catalog files.
What exactly did you expect / hope would happen by changing Marker to Markers in that call?
