In February 2018 we made the long-awaited move to art2 and ROOT6
4 1 Gavin Davies
Specifically upgrading from art v1_17_01 --> art v2_09_06
5 1 Gavin Davies
This also brought along upgrade of nutools v1_21_11 --> v2_18_01

7 1 Gavin Davies
We now pull novaddt/novadaq packages into novasoft instead of using ups products that contain these

9 1 Gavin Davies
Tensorflow is now available in the offline for deep learning development efforts.

An extensive list of fhicl deprecations is listed on the "art redmine page":https://cdcvs.fnal.gov/redmine/projects/art/wiki under "Deprecations".

Specific fhicl changes of note in novasoft are the following:

Make a note for cases that use

The code in art2 had a bit of a restructuring. The locations of product-reading libraries and headers have migrated to canvas.

35 8 Gavin Davies
Here are a few changes you're most likely to see/need:

h1. CAFAna macros
41 2 Gavin Davies
42 7 Erica Smith
h2. New Features
43 7 Erica Smith
44 5 Gavin Davies
h3. Compilation
45 5 Gavin Davies
46 5 Gavin Davies
Don't be alarmed by the increase in the number of files produced when compiling CAFAna macros.
47 2 Gavin Davies
You should see three as opposed to the previous 2 that look like this:
48 2 Gavin Davies
<pre>
49 2 Gavin Davies
Compiling test.C produces:
50 2 Gavin Davies
51 2 Gavin Davies
test_C.d
52 2 Gavin Davies
test_C.so
53 2 Gavin Davies
test_C_ACLiC_dict_rdict.pcm
54 1 Gavin Davies
</pre>
55 5 Gavin Davies
56 5 Gavin Davies
h3. Compilation errors
57 4 Gavin Davies
58 4 Gavin Davies
One gets more useful error messaging when running a macro with missing arguments.
59 4 Gavin Davies
Example:
60 4 Gavin Davies
<pre>
61 4 Gavin Davies
Info in <TUnixSystem::ACLiC>: creating shared library /nova/app/users/gsdavies/dev/./DataMCNDLoad_nus17_C.so
62 4 Gavin Davies
input_line_84:2:2: error: no matching function for call to 'DataMCNDLoad_nus17'
63 4 Gavin Davies
 DataMCNDLoad_nus17()
64 4 Gavin Davies
 ^~~~~~~~~~~~~~~~~~
65 4 Gavin Davies
././DataMCNDLoad_nus17.C:53:6: note: candidate function not viable: requires single argument 'outfile', but no
66 4 Gavin Davies
      arguments were provided
67 1 Gavin Davies
void DataMCNDLoad_nus17(std::string outfile)

h2. Harmless Warnings 
72 7 Erica Smith
73 7 Erica Smith
This section documents new warnings that may pop up, but should not affect the successful completion of your macro.
74 7 Erica Smith
75 7 Erica Smith
h3. TTreeFormula support only 2 level of variables size collections
76 7 Erica Smith
77 7 Erica Smith
If you are seeing warnings similar to:
78 7 Erica Smith
79 7 Erica Smith
<pre>
80 7 Erica Smith
Warning in <TTreeFormula::DefinedVariable>: TTreeFormula support only 2 level of variables size collections.  Assuming '@' notation for the collection bpf.
81 7 Erica Smith
Warning in <TTreeFormula::DefinedVariable>: Missing class for rec.vtx.elastic[0].fuzzyk.png[0].@bpf.at(1).pdg!
82 7 Erica Smith
</pre>
83 7 Erica Smith
84 7 Erica Smith
This is due to accessing more than 2 vectors in your variable (in this example: vertices, prongs, tracks).

h2. Potential changes
87 7 Erica Smith
88 7 Erica Smith
This section documents changes you may need to make to your macro as a result of switching to root6.

h3. Fitting errors
91 6 Erica Smith
92 6 Erica Smith
If you are fitting a histogram and getting the error message 
93 6 Erica Smith
94 6 Erica Smith
<pre>Warning in <Fit>: Fit data is empty</pre> 
95 6 Erica Smith
96 6 Erica Smith
but your histogram is not empty, check to see if your bin errors are equal to 0 with <pre>h->Print("all");</pre>
97 6 Erica Smith
98 6 Erica Smith
which will output something like this:
99 6 Erica Smith
100 6 Erica Smith
<pre>
101 6 Erica Smith
TH1.Print Name  = cafanauniq86, Entries= 1, Total sum= 102.998
102 6 Erica Smith
 fSumw[0]=0, x=-1.10917, error=0
103 6 Erica Smith
</pre>
104 6 Erica Smith
105 6 Erica Smith
If they are 0, setting <pre>h->Sumw2(kFALSE);</pre> should solve the problem.
