Thanks for your help Corona688, I'm sorry, using -tcsh on RedHat.
I think the problem is more related with #BSUB itself, because in some other part of the code I have things like:
#! bin/tcsh -f
set VAR_1 = 5
set VAR_1 = 10
@ sum = VAR_1 + VAR_2
and that works alright

I can't post links yet, but if you google bsub you'll find its man page straight away.
It can accept commands through the command line like:
>bsub -n 10
or through standard input doing
>bsub < myscript.lsf
they way bsub reads commands from standard input is by including the keyword #BSUB on the file, so you would have to write on it:
#! /bin/tcsh -f
#BSUB -n 10
I think that the problem is that when I write inside myfile.lsf:
#! /bin/tcsh -f
set NPROC = 10
#BSUB -n $NPROC
The variable $NPROC is being read as a string on standard input, instead of as a variable.
anyone with an idea of how to solve this? I'm running red had linux and TC shell
Thanks!

statistics::basic::leastsquarefit
Statistics::Basic::LeastSquareFit(3pm) User Contributed Perl Documentation Statistics::Basic::LeastSquareFit(3pm)
NAME
Statistics::Basic::LeastSquareFit - find the least square fit for two lists
SYNOPSIS
A machine to calculate the Least Square Fit of given vectors x and y.
The module returns the alpha and beta filling this formula:
$y = $beta * $x + $alpha
for a given set of x and y co-ordinate pairs.
Say you have the set of Cartesian coordinates:
my @points = ( [1,1], [2,2], [3,3], [4,4] );
The simplest way to find the LSF is as follows:
my $lsf = lsf()->set_size(int @points);
$lsf->insert(@$_) for @points;
Or this way:
my $xv = vector( map {$_->[0]} @points );
my $yv = vector( map {$_->[1]} @points );
my $lsf = lsf($xv, $yv);
And then either query the values or print them like so:
print "The LSF for $xv and $yv: $lsf
";
my ($yint, $slope) =
my ($alpha, $beta) = $lsf->query;
LSF is meant for finding a line of best fit. $beta is the slope of the line and $alpha is the y-offset. Suppose you want to draw the
line. Use these to calculate the "x" for a given "y" or vice versa:
my $y = $lsf->y_given_x( 7 );
my $x = $lsf->x_given_y( 7 );
(Note that "x_given_y()" can sometimes produce a divide-by-zero error since it has to divide by the $beta.)
Create a 20 point "moving" LSF like so:
use Statistics::Basic qw(:all nofill);
my $sth = $dbh->prepare("select x,y from points where something");
my $len = 20;
my $lsf = lsf()->set_size($len);
$sth->execute or die $dbh->errstr;
$sth->bind_columns( my ($x, $y) ) or die $dbh->errstr;
my $count = $len;
while( $sth->fetch ) {
$lsf->insert( $x, $y );
if( defined( my ($yint, $slope) = $lsf->query ) {
print "LSF: y= $slope*x + $yint
";
}
# This would also work:
# print "$lsf
" if $lsf->query_filled;
}
METHODS
This list of methods skips the methods inherited from Statistics::Basic::_TwoVectorBase (things like insert(), and ginsert()).
new()
Create a new Statistics::Basic::LeastSquareFit object. This function takes two arguments -- which can either be arrayrefs or
Statistics::Basic::Vector objects. This function is called when the leastsquarefirt() shortcut-function is called.
query()
LSF is meant for finding a line of best fit. $beta is the slope of the line and $alpha is the y-offset.
my ($alpha, $beta) = $lsf->query;
y_given_x()
Automatically calculate the y-value on the line for a given x-value.
my $y = $lsf->y_given_x( 7 );
x_given_y()
Automatically calculate the x-value on the line for a given y-value.
my $x = $lsf->x_given_y( 7 );
"x_given_y()" can sometimes produce a divide-by-zero error since it has to divide by the $beta. This might be helpful:
if( defined( my $x = eval { $lsf->x_given_y(7) } ) ) {
warn "there is no x value for 7";
} else {
print "x (given y=7): $x
";
}
query_vector1()
Return the Statistics::Basic::Vector for the first vector used in the computation of alpha and beta.
query_vector2()
Return the Statistics::Basic::Vector object for the second vector used in the computation of alpha and beta.
query_mean1()
Returns the Statistics::Basic::Mean object for the first vector used in the computation of alpha and beta.
query_variance1()
Returns the Statistics::Basic::Variance object for the first vector used in the computation of alpha and beta.
query_covariance()
Returns the Statistics::Basic::Covariance object used in the computation of alpha and beta.
OVERLOADS
This object is overloaded. It tries to return an appropriate string for the calculation, but raises an error in numeric context.
In boolean context, this object is always true (even when empty).
