Hi Cécile,
<div class=""><br class="">
</div>
<div class="">Thank you so much for looking into this. We actually have more 50k visits already uploaded into LORIS, however we have used a set of 333 “visit labels”:</div>
<div class=""><br class="">
</div>
<div class="">
<div style="margin: 0px; font-stretch: normal; font-size: 11px; line-height: normal; font-family: Menlo; color: rgb(0, 0, 0);" class="">
<span style="font-variant-ligatures: no-common-ligatures" class="">mysql> select count(*) from visit;</span></div>
<div style="margin: 0px; font-stretch: normal; font-size: 11px; line-height: normal; font-family: Menlo; color: rgb(0, 0, 0);" class="">
<span style="font-variant-ligatures: no-common-ligatures" class="">+----------+</span></div>
<div style="margin: 0px; font-stretch: normal; font-size: 11px; line-height: normal; font-family: Menlo; color: rgb(0, 0, 0);" class="">
<span style="font-variant-ligatures: no-common-ligatures" class="">| count(*) |</span></div>
<div style="margin: 0px; font-stretch: normal; font-size: 11px; line-height: normal; font-family: Menlo; color: rgb(0, 0, 0);" class="">
<span style="font-variant-ligatures: no-common-ligatures" class="">+----------+</span></div>
<div style="margin: 0px; font-stretch: normal; font-size: 11px; line-height: normal; font-family: Menlo; color: rgb(0, 0, 0);" class="">
<span style="font-variant-ligatures: no-common-ligatures" class="">| 333 |</span></div>
<div style="margin: 0px; font-stretch: normal; font-size: 11px; line-height: normal; font-family: Menlo; color: rgb(0, 0, 0);" class="">
<span style="font-variant-ligatures: no-common-ligatures" class="">+----------+</span></div>
</div>
<div class=""><br class="">
</div>
<div class="">Now we would like to create thousands of “visit labels” to upload more visits. Apparently it should be fine but we would like to be sure that LORIS can handle them without any issues. I can recall that at some point there was a limitation on the
number of centers that could be handle, witch was about 512 but got fixed. We just want to double check with the LORIS DevTeam that there are no limitations on this.</div>

Hi Alfredo,
<div class=""><br class="">
</div>
<div class="">I just looked into the number of visits of a longitudinal project we have. Currently, they have 8698 visits in the session table and everything works well. I believe they are now 10 years after baseline as well (although the pandemic reduced a
little bit the number of visits during 2020 for the project as you can imagine). </div>
<div class=""><br class="">
</div>
<div class="">Based on this, I would not expect any major issues.</div>
<div class=""><br class="">
</div>
<div class="">Hope this helps,</div>

<div class="">I don't know of any limits or reasons why thousands of visits would be a problem. However I also don't know of any projects handling that many visits. I will run it by the LORIS team at our meeting today and see if anyone has more accurate information.</div>

Dear LorisDev Team,<br class="">
<br class="">
We are planning on adding visit labels in days, for instance the visit label “d3650" will correspond to a visit 10 years after baseline. This will imply the creation of thousands of visits, is there a limit on the number of visits that can be added to LORIS?
This is required for a retrospective study that we are going to upload into LORIS.<br class="">
<br class="">
Best regards,<br class="">
Alfredo.<br class="">
