Hi Nicolas,
<div><br>
</div>
<div>We are working on this issue but a question. Sometimes studies have dual echo and dynamic sequences (e.g., <span style="color:rgb(0,0,0)">a dual-echo PD/T2 sequence produces a PD-weighted image and a T2-weighted
image together</span>) that result in in two sequences sharing the same “ <span style="color:rgb(0,0,0)">SeriesInstanceUID</span>”. This seems to be quite common, don’t you have a workaround already available in LORIS?</div>
<div><br>
</div>
<div>Best,</div>
<div>Alfredo.</div>

<div dir="ltr">Hi Alfredo,
<div><br>
</div>
<div>You cannot insert in the database a scan archive containing two different study UIDs: all the scans inside the archive must have the same study UID, that's a LORIS requirement. I suggest you split your original archive into two archives, based
on their study UIDs, and then upload/insert both. You could also "hack" you original archive so that all study UIDs are identical but I am not a big fan of this strategy since you are altering the original data you got from the scanner...</div>

<div>Best,</div>

<div><br>
</div>
<div>p.s: if you are not comfortable splitting archives, I can help</div>

<div>Dear LORIS-Dev Team,
<div><br>
</div>
<div>In the IPMSA project some scans have acquisitions with two different <font>StudyInstanceUIDs. This leads to an error in the insertion pipeline. The reason for having two different </font><span>StudyInstanceUIDs is because
some</span><font> acquisitions failed QC and were re-acquired and added to the same study but with a <span>different</span> <span>StudyInstanceUIDs. Here are our questions:</span></font></div>
<div><font><span><br>
</span></font></div>
<div><font>1. Would it be possible to insert a study having acquisitions with two different </font><span>StudyInstanceUIDs?</span></div>
<div><span><br>
</span></div>
<div><span>2. If we were to change the </span><font>StudyInstanceUIDs to have only one in a study, would LORIS insert they study with acquisitions having different scan date?</font></div>
<div><font><br>
</font></div>
<div><font>Thank you for your help.</font></div>
<div><font><br>
</font></div>
<div><font>Regards,</font></div>
<div><font>Alfredo.</font></div>
