== Motivation and Format of the Clinic ==
  
 
'''The Clinic is a HANDS-ON discussion-based workshop. The people who should attend the AMS Clinic are those who are directly using the AMS and doing (or are VERY involved in directly supervising) AMS data analysis of field or lab data. The clinic will be much less useful for PIs who are not directly involved in directly using the instrument and doing data analysis, or for people who are just starting to learn about the AMS but haven't done serious instrument use and data analysis yet. Attendees are expected to bring to the Clinic datasets in which they are currently working, and be ready to use them as a basis for discussion with the group.'''

''' Recipe for a mass defect plot (you can choose to put a chocolate cake underneath it or not :) )'''
 +
** We want at these 4 items for the "mise en place"
 +
** (A) The x axis wave is the exact mass wave, the wave of all the ions that were chosen to fit.
 +
** (B)The y axis wave is the mass defect wave, the wave that indicates the difference between the a pure carbon fragment and the mass offsets due to the Hs, Cs, etc.
 +
** (C)The f(z) wave for the size of the markers will be the sqrt(log(HR peak stick)). However, log of stick values may be negative, and the sqrt of a negative is a nans, so we will have to adjust this wave that reflects size (usually markers, hence the sqrt) to be non-nan.  
 +
** (D)The f(z) wave for the color of the markers will be the family colors
 +
 +
 
 +
The first set of instructions will be a mass defect plot to be made for the sticks calculated by the gold button press "Calc HR sticks for one set of spectra
 +
* duplicate/o root:HR_sticks:ExactMassWave root:OneRunMassDefect
 +
* root:OneRunMassDefect = root:HR_sticks:ExactMassWave - round(root:HR_sticks:ExactMassWave)
 +
* duplicate/o root:HR_sticks:OneRunStickDiff root:LogOneRunDiffStick
 +
* LogOneRunDiffStick = log(root:HR_sticks:OneRunStickDiff
 +
* duplicate/o root:HR_sticks:OneRunStickDiff OneRunFamilyColorCode
 +
* OneRunFamilyColorCode = sq_findStr(root:HR:HR_familyName,root:HR_sticks:ExactMassFamilyText[p],1)
 +
 
 +
 
 +
// Now to make the graph & prettify it:
 +
* display OneRunMassDefect vs root:HR_sticks:ExactMassWave
 +
* ModifyGraph zmrkSize(OneRunMassDefect)={LogOneRunDiffStick,*,*,1,10}
 +
* ModifyGraph zColor(OneRunMassDefect)={OneRunFamilyColorCode,*,*,dBZ21,0}
 +
* Label left "mass defect";
 +
* Label bottom "m/z"
 +
* ModifyGraph mode=3,marker=19
 +
 +
The second set of instructions will be a mass defect plot to be made for the sticks calculated with an HR spectra of species (i.e. from the results tab... in this example my wave is called MSSM_all_HROrg)
 +
* duplicate/o root:HR_frag:SpeciesMassWave root:MassDefect_MSSM_all_HROrg
 +
* root:MassDefect_MSSM_all_HROrg = root:HR_frag:SpeciesMassWave - round(root:HR_frag:SpeciesMassWave)
 +
* duplicate/o root:MSSM_all_HRorg root:Log_MSSM_all_HROrg
 +
* Log_MSSM_all_HROrg = log(root:MSSM_all_HROrg)
 +
* duplicate/o root:HR_sticks:OneRunStickDiff MSSM_all_HROrg_FamilyColorCode
 +
* MSSM_all_HROrg_FamilyColorCode = sq_findStr(root:HR:HR_familyName,root:HR_frag:SpeciesFamilyText[p],1)

Motivation and Format of the Clinic

The Clinic is a HANDS-ON discussion-based workshop. The people who should attend the AMS Clinic are those who are directly using the AMS and doing (or are VERY involved in directly supervising) AMS data analysis of field or lab data. The clinic will be much less useful for PIs who are not directly involved in directly using the instrument and doing data analysis, or for people who are just starting to learn about the AMS but haven't done serious instrument use and data analysis yet. Attendees are expected to bring to the Clinic datasets in which they are currently working, and be ready to use them as a basis for discussion with the group.

Dates and Location

The 5th AMS Instrument and Data Analysis Clinic and 2nd Aerodyne CIMS Meeting and Clinic will take place in the Spring of 2013 at the University of Colorado-Boulder. They are organized by the Jimenez Group and Aerodyne, and also sponsored by CIRES.

Recipe for a mass defect plot (you can choose to put a chocolate cake underneath it or not :) )

    • We want at these 4 items for the "mise en place"
    • (A) The x axis wave is the exact mass wave, the wave of all the ions that were chosen to fit.
    • (B)The y axis wave is the mass defect wave, the wave that indicates the difference between the a pure carbon fragment and the mass offsets due to the Hs, Cs, etc.
    • (C)The f(z) wave for the size of the markers will be the sqrt(log(HR peak stick)). However, log of stick values may be negative, and the sqrt of a negative is a nans, so we will have to adjust this wave that reflects size (usually markers, hence the sqrt) to be non-nan.
    • (D)The f(z) wave for the color of the markers will be the family colors


The first set of instructions will be a mass defect plot to be made for the sticks calculated by the gold button press "Calc HR sticks for one set of spectra

  • duplicate/o root:HR_sticks:ExactMassWave root:OneRunMassDefect
  • root:OneRunMassDefect = root:HR_sticks:ExactMassWave - round(root:HR_sticks:ExactMassWave)
  • duplicate/o root:HR_sticks:OneRunStickDiff root:LogOneRunDiffStick
  • LogOneRunDiffStick = log(root:HR_sticks:OneRunStickDiff
  • duplicate/o root:HR_sticks:OneRunStickDiff OneRunFamilyColorCode
  • OneRunFamilyColorCode = sq_findStr(root:HR:HR_familyName,root:HR_sticks:ExactMassFamilyText[p],1)


// Now to make the graph & prettify it:

  • display OneRunMassDefect vs root:HR_sticks:ExactMassWave
  • ModifyGraph zmrkSize(OneRunMassDefect)={LogOneRunDiffStick,*,*,1,10}
  • ModifyGraph zColor(OneRunMassDefect)={OneRunFamilyColorCode,*,*,dBZ21,0}
  • Label left "mass defect";
  • Label bottom "m/z"
  • ModifyGraph mode=3,marker=19

The second set of instructions will be a mass defect plot to be made for the sticks calculated with an HR spectra of species (i.e. from the results tab... in this example my wave is called MSSM_all_HROrg)

  • duplicate/o root:HR_frag:SpeciesMassWave root:MassDefect_MSSM_all_HROrg
  • root:MassDefect_MSSM_all_HROrg = root:HR_frag:SpeciesMassWave - round(root:HR_frag:SpeciesMassWave)
  • duplicate/o root:MSSM_all_HRorg root:Log_MSSM_all_HROrg
  • Log_MSSM_all_HROrg = log(root:MSSM_all_HROrg)
  • duplicate/o root:HR_sticks:OneRunStickDiff MSSM_all_HROrg_FamilyColorCode
  • MSSM_all_HROrg_FamilyColorCode = sq_findStr(root:HR:HR_familyName,root:HR_frag:SpeciesFamilyText[p],1)


// Now to make the graph & prettify it:

  • display MassDefect_MSSM_all_HROrg vs root:HR_frag:SpeciesMassWave
  • ModifyGraph zmrkSize(MassDefect_MSSM_all_HROrg )={Log_MSSM_all_HROrg,*,*,1,10}
  • ModifyGraph zColor(MassDefect_MSSM_all_HROrg)={MSSM_all_HROrg_FamilyColorCode,*,*,dBZ21,0}
  • Label left "mass defect";
  • Label bottom "m/z"
  • ModifyGraph mode=3,marker=19

Details of 5th AMS Clinic

  • As planned, this is "out of phase" with the AMS Users Meeting and the heavy Fall meeting season (AAAR, EAC, AMS Users Meeting, AGU...).
  • There is no registration fee, but please register if you are coming to plan food, coffee, tables, power, internet, name tags, hotel room block, etc.
  • Feedback from past Clinics has been very positive overall, and we try to learn every time how to make the Clinic more useful and interesting to the users. You you can see the details for 2009, 2010, and 2011, and 2012.
  • Pictures from the 5th AMS Clinic can be found here.

Logistics

  • The location will be the Ekeley Building in the CU Campus in Boulder. The location is linked here in Google Maps and here in the CU online map. The Northeast door of the building will be the only door open on Sunday. The room is Ekeley E1B20, just to the left after entering the building. It is the same location as last year.
  • All AMS days will start at 9 am and go till 5-6 pm, with a break for lunch and additional coffee breaks.
  • The University of Colorado at Boulder will be on spring break the week of Monday March 25 - Friday March 29, so there will be minimal traffic.
