 Note that 1k may be a candidate. But it just got fixed (burned out cable inthe feed box) and we need to review the recent results. JR - Feb 23, 2019

 While waiting for the storage server to be populated and configured, dsa-ata-1 has the local 8TB disk mounted in ~dsa/data for recording. The main .fil files will be stored here. The log files for data capture will be stored in ~dsa/vikram/scratch
-   - Login into dsa-ata-1
+This will capture data from the antenna in SNAP1.
-   - run ~dsa/DSA_10/scripts/setup_singleFil.py create
-   - run ~dsa/DSA_10/scripts/setup_singleFil.py start
+   - Login into dsa-ata-1 (username: dsa)
+   - run ~dsa/usr/DSA-10/scripts/setup_singleFil.py create
+   - run ~dsa/usr/DSA-10/scripts/setup_singleFil.py start
 when ready to start the observation run:
-   - ~fpga_scripts/dsa_ata_incoherent.py
+   - ~fpga_control/dsa_ata_incoherent.py

+To capture data from all 10 SNAPs:
+   - run ~dsa/usr/DSA-10/scripts/setup_multiFil10.py create
+   - run ~dsa/usr/DSA-10/scripts/setup_multtiFil10.py start
+when ready to start the observation run:

+   - ~dsa/usr/DSA-10/scripts/setup_multiFil10.py destroy
+   - ~dsa/fpga_control/dsa_ata_stop.py
+After an observation, use "filedit" to correct the start frequency and start time of the data in the filterbank file. E.g.: "filedit -T 58659.932 ./slog_57929.920.fil" and "filedit -f 1680 ./slog_57929.920.fil"
+If the FPGAs have been power cycled and need programming:
+   - cd ~dsa/fpga_control/bofs
+   - source ~jackh/venv/cfpga/bin/activate
+   - ipython
+   - import casperfpga
+   - fpga = casperfpga.CasperFpga('dsa-ata-snap-1')
+   - fpga.upload_to_ram_and_program('dsa_ata_v3_2019-06-21_1131.fpg')
+repeat for each SNAP (2-10).
+=====Status Sep 19, 2019 =====
-Everything installed and working, with the exception of GPU machine dsa-ata-4, which has developed a fault. Following up with ACME.
+All systems were working, however seem to have developed a fault with netboot. Debugging is ongoing. It may be necessary to install a local OS on each server.
-The server side software is set to by default only configure a single FPGA and take observations with only 2 inputs for testing purposes.
