Minutes:

1. Yuri has done a transfer of 7.7GeV data to disk space leased by PAC that we can use for the studies at /gpfs01/star/pwg_tasks/TF_TrkEff

2. MTD software is now running in both .DEV2 and dev and returns data trees. Only problem remains that in dev there is a spurious crash at the end after the data is saved. David is now
comparing the outputs.

3. Yang He has presented QA studies of embedding in isobar data https://drupal.star.bnl.gov/STAR/system/files/isobar_embeding_testrun_QA_March18.pdf.
There is a strange pt-dependence observed in efficiency. It was discussed and suggest to look into 2D eta-phi dependence to see if it is related to the bad TPC sector.
It was discussed the effect effect of missing TPC sector could show up through nHits cut.
It was also suggested to try simulation with realistic pt spectra since some effects could be due to reweighting.
