Multiple Imputation: dat file spacing PreviousNext

Hello, I am running a SEM model with multiple imputation, and I received the following message: "THE FOLLOWING DATA SET(S) DID NOT RESULT IN A COMPLETED REPLICATION" All 20 imputation data sets were listed as problematic. Looking through the 20 imputed data sets (dat files), I noticed that there is no space between the two variables. The first is a dummy variable and the subsequent variable is quite wide because it is an earnings variable. The imputation assigned some negative values to the earnings variable, and there is no space between variables when there is a negative sign. Does Mplus require a space between columns in the imputation data sets? If so, can I fix this problem during the imputation phase? Perhaps I can specify another file type for imputation or I can specify spacing. Would one of these options work, and if so, is there syntax for these options? Thanks in advance for any help!

Look at the end of the output where you saved the imputed data sets. You will see the order of the variables in the imputed data sets and the format. I believe the default is a fixed format.
