Good morning. I wrote the following code:
do ii=1,nnodi
read (spostamenti,*), servline(1,:) ! Leggo la stringa e l'associo all'ii-esima riga della matrice lista nodi
do i=1,int_nod_ut
if (servline(1,1)>=nod_ut_in(i,1) .and.
& servline(1,1)<=nod_ut_fin(i,1)) then
jj=jj+1;
spost_nodi(jj,:)=servline(1,2:5)
idx_spost_nodi(jj,:)=servline(1,1);
end if
enddo
end do
ii=0
jj=0 ! Inizializzo l'indice del ciclo
do ii=1,nnodi
read (veloc,*), servline(1,:) ! Leggo la stringa e l'associo all'ii-esima riga della matrice lista nodi
do i=1,int_nod_ut
if (servline(1,1)>=nod_ut_in(i,1) .and.
& servline(1,1)<=nod_ut_fin(i,1)) then
jj=jj+1;
veloc_nodi(jj,:)=servline(1,2:4)
idx_veloc_nodi(jj,:)=servline(1,1);
end if
enddo
end do
The files " spostamenti" and "veloc" are very similar. I can import the first file properly, in the second case read function reads the first line, then skip the second line, then it reads the third, skip the fourth and so on. Probably is something very stupid, but I can't understand what is wrong in this procedure.

The problem is in the read function, because writing this:
do ii=1,nnodi
read (veloc,*), servline(1,:)
write(*,*), servline(1,:)
end do
It's simple to understand that read function skips a line each time.

What are the types of the variables spostamenti and veloc? Are they of type CHARACTER or of type INTEGER?
You will need to show the source code and the data files in more detail, if you wish to obtain advice regarding what your code is doing. Without knowing what the data files contain, and without knowing the types and shapes of the variables in the I/O lists, it is almost impossible to tell what is happening.
