Dear Clothilde,

This seems to be related to variable substitution in Matlab. When you type

pos=13696;Batom=mpf(B10000,'p','"[pos:pos+1]"');

the mpf command just gets the book, the string 'p' and the string '"[pos:pos+1]"' but not the value of pos. What you need is a technique to substitute the string "pos" with its numerical value, for example using

['"[' num2str(pos) ':' num2str(pos+1) ']"' ]

I hope this helps

Best regards,

Remi.

Dear developpers

Once again thank you very much for MPTK !!
We are now trying to get further in the work and we need to use the full possibilities of the function mpf.m

but we find a very strange thing:
consider the command line

pos=13696;Batom=mpf(B10000,'p','"[pos:pos+1]"');

the command line yields the following answer:

mystring =

setenv LD_LIBRARY_PATH /usr/local/MPTK-0.5.4/lib;/usr/local/MPTK-0.5.4/bin/mpf tempbook.bin -p "[pos:pos+1]" tempyes.bin tempno.bin

So it is clear that mpf doesn't select nothing.

Then the other command line

Batom=mpf(B10000,'p','"[13696:13697]"');

It yields

So it selected the atoms.

could you help us to fix this problem ???
Thank you very much by advance
with best regards
