<div style="word-wrap:break-word">Dear Krzysztof,
<div><br>
</div>
<div>thanks a lot for the report.</div>
<div><br>
</div>
<div>Indeed, as you correctly spotted, there was a missing allocation in the specific case with num_exclude_bands > 0. </div>
<div>Actually, the same problem was also present in the routine reading from a formatted file, needed for the conversion in the opposite format.</div>
<div><br>
</div>
<div>I committed the correction to the Wannier CVS and this will be distributed with the next Wannier90 release.</div>
<div>Would you be so kind to check if the attached w90chk2chk.F90 (which is the fixed version) works for you, when converting in both directions (e.g. you can convert to formatted, then back to unformatted, and see if you are e.g. still able to restart from
the chk file generated with the roundtrip and obtain the same results).</div>
<div><br>
</div>
<div>Thank you in advance,</div>
<div>Giovanni Pizzi</div>

Dear All,<br>
I was recently trying to convert my seedname.chk to seedname.chk.fmt using utility tool: w90chk2chk.x. I was able to run tests provided without any errors. I also was able to produce seedname.chk.fmt for both test1 and test2.<br>
<br>
Now I am trying to do NiO benchmark (paramagnetic calculations) and do later on to use of this for DMFT calculations. When runnig w90chk2chk.x I got segmentation fault. I have added two lines to w90chk2chk.f90:<span class="x_Apple-converted-space"> </span><br>
<br>
allocate(exclude_bands(num_exclude_bands),stat=ierr) ! ****KD*****<br>
if (ierr/=0) call io_error('Error allocating exclude_bands in param_read') !*****KD*****<br>
<br>
And it seems to work for my benchmark. In the attachment FILES I am sending you the main inptu/output files from the run with modified w90chk2chk.f90.<br>
<br>
Without modification I get the following error while runnig w90chk2chk.x:<br>
<br>
forrtl: severe (174): SIGSEGV, segmentation fault occurred<br>

I have attached log file from w90chk2chk (w90chk2chk_vannila.logż<span id="x_spnAtmt" tabindex="-1"><span class="x_delLnk"></span></span><span id="x_spnAtmt" tabindex="-1"></span>) from run without any modifications. It stops at work after reading bands.<br>
<br>
<br>
I have compiled wannier90 using the following settings:<br>
F90 = /opt/intel/bin/ifort<br>
#COMMS=<br>
MPIF90=/opt/intel/impi/5.0.3.048/bin64/mpif90<br>
FCOPTS=-O2 -heap-arrays -g -traceback<span class="x_Apple-converted-space"> </span><br>
LDOPTS=-O2 -g -traceback<span class="x_Apple-converted-space"> </span><br>
<br>
LIBDIR = /opt/intel/mkl/lib/intel64<br>
LIBS = -L$(LIBDIR) -lmkl_core -lmkl_intel_lp64 -lmkl_sequential -lpthread<br>
<br>
Is there a problem with my compilation or have I found a bug?<br>
<br>
Regards,<br>
