CWAT tests (factory tests), we discovered that our Falcon 4i camera
shows a total number of 4 dead pixels lines from which 2 of them are
adjacent and placed in the center of the sensor (have a look at the
image attached). <br>Note that the image was binned 4x in order to be able to pass by email (size limitation).<br>Considering
that our Glacios will be used not only for single particles, but also
for tomography imaging of lamellas and cells, we would like to have your
input (thoughts), concerning the problems that those 2 consecutive dead
pixels lines will cause during the image analysis of the data and their
impact on the data quality.<br>My best regards,<br>-- <br>Ana Andreea ARTENI, PhD<br>********************************<br>UMR 9198 Institut de Biologie Intégrative de la Cellule<br>Plateforme de cryo-microscopie électronique<br>Responsable technique<br>Bâtiment 14B (RDC. pièce 111)<br>1 avenue de la Terrasse<br>91198 Gif-sur-Yvette Cedex, FRANCE<br>Phone: + <span class="ydp553c55deObject" id="ydp553c55deOBJ_PREFIX_DWT391_com_zimbra_phone"><a href="callto:33 (0)1 69 82 38 56" rel="nofollow" target="_blank">33 (0)1 69 82 38 56</a></span><br>Fax: <span class="ydp553c55deObject" id="ydp553c55deOBJ_PREFIX_DWT392_com_zimbra_phone"><a href="callto:+33 (0)1 69 82 43 08" rel="nofollow" target="_blank">+33 (0)1 69 82 43 08</a></span><br>E-mail : <span class="ydp553c55deObject" id="ydp553c55deOBJ_PREFIX_DWT393_ZmEmailObjectHandler"><span class="ydp553c55deObject" id="ydp553c55deOBJ_PREFIX_DWT395_ZmEmailObjectHandler">ana-andreea.arteni@i2bc.paris-saclay.fr</span></span><br>Site web: <span class="ydp553c55deObject" id="ydp553c55deOBJ_PREFIX_DWT394_com_zimbra_url"><span class="ydp553c55deObject" id="ydp553c55deOBJ_PREFIX_DWT396_com_zimbra_url"><a href="https://urldefense.com/v3/__https://www.i2bc.paris-saclay.fr/structural-biology/cryoem/__;!!Mih3wA!CvMj30hsNSMt3E1BDTUHEsvM4X4txRTqbRJ1XO3RkkNd_vkGJE2ffvjeQ7j7eALM54rMj5rhLFoM9VqFIg$" rel="nofollow" target="_blank">https://www.i2bc.paris-saclay.fr/structural-biology/cryoem/</a></span></span></div><br><img title="Inline image" alt="Inline image" src="cid:d8903362-9232-1921-f629-200aeddac797@yahoo.com" class="yahoo-inline-image" style="max-width: 800px; width: 100%;" draggable="false" data-id="<d8903362-9232-1921-f629-200aeddac797@yahoo.com>"><br></div></div></body></html>
