is there any difference between .xls and .mat

[insolven]

dear users:

1) I estimate one simple model and use 35 observations stored in data.xls. but when i beging estimate routine, dynare says:
.....
The rank condition is verified.
Loading 34 observations from data.xls
.......
Estimation::mcmc: Posterior (dsge) IRFs...
Estimation::mcmc: Posterior IRFs, done!
Loading 34 observations from data.xls
......

why less than 35 observations? and i set [nobs=35], that problem is still remain.

and when i restore the same 35 observations in data.mat, dynare says:

Estimation::mcmc: Posterior (dsge) IRFs...
Estimation::mcmc: Posterior IRFs, done!
Loading 35 observations from data.mat

2) loading different numbers of observations , why?

Please try Dynare 4.4.3. There was a bug in 4.4.2 that prevented loading the first observation.

Please try Dynare 4.4.3. There was a bug in 4.4.2 that prevented loading the first observation.

Here is a list of the problems identified in version 4.4.2 and that
have been fixed in version 4.4.3:


- When loading a dataset in XLS, XLSX or CSV format, the first
observation was discarded.



thanks a lot,,,, dear jpfeifer
