    * There are many computers/workstations in Kamioka site or Kamioka control room.
    * Workstations (k1ctr*) use common conda environment by mounting the file server.
    * In DetChar computers k1{sum,det}[01], conda environment should be unified all DetChar resources, similar to workstations.
    * To prevent the trouble that DetChar experts might break the environment, the conda environments will be set as read-only permission.
    * Installation will be done by Kamioka members. After that, we need volunteers to test the DetChar tools on new conda environment.
    * what is the time line?
     * Installation will finished before the end of March. From April, the test will start. Volunteers are helpful.
   * DQ flags for O4
    * In last PEM meeting, Yuzurihara presented the current status and received the helpful comments. [slide](https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=13970)
    * We will change our plan to construct the data quality flag and will compute the BLRMS of gwpy to set the threshold.
    * The review is necessary before O4. (probably very close to O4, because we need ER)
   * DQR update
    * no update
   * Commissioning of GreenX
    * In the last weekend, the commissioner tried continuous GreenX. During that trials, they found many short term lock loss (~10 ms). 10 ms is too short to follow the suspension motion, so it is likely that there are some causes of the lock loss except for the suspension motion.
    * The commissioner needs helps DetChar members to identify the cause or give a hint of the cause.
    * For details, see [[https://klog.icrr.u-tokyo.ac.jp/osl/index.php?r=19963|klog#19963]] [[https://klog.icrr.u-tokyo.ac.jp/osl/index.php?r=19983|klog#19983]]

     * no update
    * DQ flags for O4
     * no update
    * progress of DQR
     * igwn-alert is running more than 9days and receiving the MDC alert
     * next step is to connect the MDC alert with the launch TaskManager.
     * remained task is to develop InspiralRange [[https://git.ligo.org/detchar/dqrtasks/-/issues/8|issue]]
    * lock loss study of GreenX
     * [[https://klog.icrr.u-tokyo.ac.jp/osl/?r=19906|klog#19906]]
     * From the Hveto result, the channel (K1:IMC-SERVO_MIXER_DAQ_OUT_DQ) was the most coincident channel with the lock loss of GreenX.
    * unify the detchar computing environment (YamaT)
     * scattered codes and applications (Omicron, summary page, ) over Kamioka computers are troubling.
     * we plan to unify the environment by using igwn conda
     * detail will be reported in next meeting
     * (Darkhan) conda environment on k1ctr*. someone accidentally update someone's conda environment. administrator should prepare the conda environment?
     * (YamaT) k1ctr* share the environment. this activity is not related to k1ctr* but k1sum[01], k1det[012]. we should separate the user environment and the environment for the DET tools
     * (Darkhan) should avoid accidental mistake.

       * hopefully after july, there will be lock trial for two monthes(?)
      * When you set the 1% criteria, always you throw away the 1% data?
