Hi Mollie,<br>
<br>
It takes a couple of more things to get ofstream properly working in
ADMB code. First, in the GLOBALS_SECTION, you must include the
ofstream header files. What I usually do is use
#include<admodel.h> since this will include the fstream files as
well as others that will eventually be necessary. Second, define the
ofstream (what you call out_stream) in the GLOBALS_SECTION, but do not
open it. Then, I open the ofstream in the PRELIMINARY_CALCS_SECTION,
write any headers to the file, then close it. Finally, in the
PROCEDURE_SECTION, I open the ofstream file with an append, write out,
then close it. This way, you get ouput from every iteration. By opening
the ofstream in different sections, you can output different points in
the minimization.<br>
<br>
I see that Steve has just answered this question (I'm a bit slow at
times), but I thought I would post a "simple" example of how I perceive
the process (see below).<br>
<br>
Good luck,<br>
Allan<br>

f=(norm2(pred_Y-Y)); <br>
f=nobs/2.*log(f); // make it a likelihood function so that<br>
// covariance matrix is correct<br>
out_stream.open("trial.txt",ios::app); //append to file<br>
out_stream << "test: " << f << endl;<br>
out_stream.close();<br>

<div>Hi Steve,</div>
<div>I'm still getting this error:</div>
<div>
<div>admbponds_measurment_trial.cpp:1: error: ‘ofstream’ does not
name a type</div>
</div>
<div><br>
</div>
<div>to go with this first line of the .cpp file:</div>
<div>ofstream out_stream("/scratch/ufhpc/mbrooks/trial.txt");</div>
<div><br>
</div>
<div>I'm wondering if it's a problem that the GLOBALS_SECTION puts
this definition before #include <admodel.h>?</div>
<div>I'm wondering if <admodel.h> contains the relevant
iostream info.</div>
