A: In iOGAS 5.0, to prevent the old projection files from being overwritten, we have renamed these files. The new projection files are appended with a .1 suffix and ioGAS 5.0 reads from these files. For ioGAS to be able to read your custom projections, you will need to move these projections over to the new projection files. You can do this by simply copy and pasting the projections to the appropriate files.
