    * (yamat) How do you decide clustering length?
    * (Narikawa) By software injection, we can evaluate how the SNR spreads and determine the clustering length.

      * There may be also no compatibility between SummaryPages we use and omicron in igwn-py39.
      * If so, we need to move igwn-py39 for all tools (SummaryPages, omicron, hveto etc.)

          * Not included in IGWN environment?
      * Problem
        * No global NDS2, DataFind servers or equivalent way.
          * SSH port forwarding is not enough because port number is different depending on person.
          * So I cannot do the code hack on IGWN software in the system region.
        * KAGRA env may not be able to be included in IGWN until O4.
          * If so, we shouldn't use IGWN in officially for O4.
     * (Lupin) igwn-py38? or py39?
     * YamaT asked status of FScan
     * In future, we need to prepare similar environment on Kashiwa cluster. The environment is not completely same as Kamioka computers.
     * We need volunteers from remote site, to test hveto and FScan. Please let us (Yuzuriahra or YamaT) know.
    * DQR update (Yuzurihara)
     * Operation test for new version of Task Manager is on-going on k1det1.
     * I found that code of stationary task uses `datafind` to read gwf data, which we don't have.
     * I need to consider how to read data for DQR tasks.
      * (Darkhan) Is there any way to get the latest list of channels?
      * (Yuzurihara) If you can specify the name of frame data, there is a function on gwpy.

   * unify conda environment in Kamioka detchar computers, k1sum[01] and k1det[012] (YamaT)
    * 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]]

     * 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.
