<p style="margin: 0 0 1em 0; color: black;">Hi Mohamed, </p>
<p style="margin: 0 0 1em 0; color: black;">I solved a structure at 1.5 A
with Sulfur MAD. There were only 4 Sulfurs in the sequence and the signal
has very nice. </p>
<p style="margin: 0 0 1em 0; color: black;">Pay attention S does not give
high anomalous signal.</p>
<p style="margin: 0 0 1em 0; color: black;">I suggest you collect a dataset
at 7kev (around 2.0A) which is the absorption edge of S. You must collect
very high multiplicity around 30-40 times with low intensity beam not to
burn the crystal. This at kappa 0 and kappa 45. Then you could merge both
datasets. I remember an important thing, on the absorption edge we had to
be careful on the harmonics and make a nice setting on the beam to remove
them. I suggest you do also a collection at 14kev far away from absorption
edge. </p>
<p style="margin: 0 0 1em 0; color: black;">For my case only Autorickshaw
found the Sulfurs and solve the problem of phases. </p>
<p style="margin: 0 0 1em 0; color: black;">Hope it helps, <br>
Ivan <br><br></p>
