"instruction": "For this task, start with a complete NREL 5 MW ROSCO controller input `/home/user/Desktop/DISCON.IN`, the OpenFAST model `/home/user/Desktop/rosco_base.fst`, the ROSCO v2.10.5 Linux controller library `/home/user/Desktop/libdiscon.so`, and its rotor-performance table. Additional initialization dependencies are pre-uploaded under `/home/user/Desktop` with relative structure preserved. Only initialization inputs are included; no answer/result artifacts are preloaded. Run `/home/user/miniconda3/bin/openfast` from a terminal.\n\nComplete a two-case pitch-controller gain study from the command line: 1. Generate `/home/user/Desktop/rosco_soft.IN` and `/home/user/Desktop/rosco_stiff.IN`. Preserve `PC_GS_n=30`, `PC_GS_angles`, and every non-pitch-gain setting. In both `PC_GS_KP` and `PC_GS_KI`, multiply every one of the 30 signed baseline values by 0.5 for the soft case and by 1.5 for the stiff case; do not replace these ROSCO gain-schedule arrays with legacy scalar `PC_Kp`/`PC_Ki` fields. 2. Copy the supplied ElastoDyn and AeroDyn inputs to `/home/user/Desktop/elasto_rosco.dat` and `/home/user/Desktop/aero_rosco.dat`, changing their old `../5MW_Baseline/` references to `5MW_Baseline/`. Generate matching ServoDyn files `/home/user/Desktop/servo_soft.dat` and `/home/user/Desktop/servo_stiff.dat` that load `libdiscon.so` and the corresponding controller input. Generate `/home/user/Desktop/rosco_soft.fst` and `/home/user/Desktop/rosco_stiff.fst` from `rosco_base.fst`; reference these local module copies, use the supplied 12 m/s TurbSim wind input, set `TMax=60 s`, `DT_Out=0.1 s`, and text output (`OutFileFmt=1`). 3. Run both cases with OpenFAST 5.0.0 and save terminal logs as `/home/user/Desktop/rosco_soft.log` and `/home/user/Desktop/rosco_stiff.log`. 4. Write `/home/user/Desktop/postprocess.py` and compute population standard deviations over the inclusive `t=10.0...60.0 s` window (501 native samples) for `RotSpeed` in rpm, `BldPitch1` in degrees, and `GenPwr` in kW. 5. Save exactly one comma-separated row to `/home/user/Desktop/summary.txt` in this order: `soft_rpm_std,stiff_rpm_std,soft_pitch_std,stiff_pitch_std,soft_power_kw_std,stiff_power_kw_std`. 6.
